High Performance Fuse for Automotive Applications
With the AMO 10.3x38, Schurter launches a high-performance fuse for particularly high voltages up to 800 VDC and currents up to 50 A, which is particularly suitable for automotive applications.
High voltages and high currents occur in electric vehicles in numerous places. Their battery packs with several thousand rechargeable cells store enormous amounts of energy. This in order to meet customer requirements concerning driving performance and range by still providing the shortest possible recharging times. To safeguard this level of power, you need highly reliable high power fuses. Such fuses are required, for example, in the BMS (Battery Management System), for on-board and off-board chargers, DC-DC converters and other systems exposed to high voltages.
Welding Is More Reliable
A weak point of every fuse is the connection between the melting wire and the contact cap. This connection is usually done by a solder joint. In the fuse production process, however, this technology brings quite many difficulties. Creating the connection by welding increases the reliability by far. SCHURTER uses a new, patented process which guarantees highest reliability.
Versatile Mounting Options
The new fuses of the AMO series offer a multitude of possible mounting options. In addition to the classic mounting directly on a printed circuit board, screwable version for surface mounting or even axial mounting are available.

Supercaps, also known as supercapacitors, are a special type of energy storage device that combine certain properties of rechargeable batteries with those of capacitors. They can store enormous amounts of energy this way and release it again very quickly, which makes them particularly valuable for many applications.
Compared to rechargeable batteries of the same weight, supercapacitors only have around 10 % of the energy density. However, their power density is around ten to a hundred times greater. Supercapacitors can therefore be charged and discharged much faster. They also withstand many more charging cycles than rechargeable batteries and are therefore suitable as a replacement or supplement wherever high switching loads are required.
Power Density vs Energy Density
The power density describes how quickly an energy storage device can release or store energy. It is crucial for applications that require short-term high energy outputs, such as when starting an engine. Supercapacitors are characterized by a high power density, which is why they can provide energy very quickly. The energy density indicates how much energy a storage device can hold over a longer period of time. A high energy density is essential for applications that require a continuous energy supply.
World's Thinnest Supercapacitors
The prismatic supercapacitors from Schurter are super-thin. With a thickness of just 0.4 mm, the Schurter SCPA is currently the world's thinnest supercapacitor.
Applications
The new supercapacitors from Schurter are ideal for demanding applications that require high capacitance in the most compact dimensions. For example, in mobile devices, wearable electronics, sensor technology, small power supplies or devices with mobile energy generation and uninterruptible power supplies.

Innovation Unveiled: Schurter EDC Electronic Switch for High DC Currents - A Preview into the Future of DC Switching
The Electronic Direct Current Switch (EDC) is a new product that is an electro-mechanical microswitch that has been developed specifically for switching high direct currents. The EDC is currently the only one of its kind. Super-compact and lightweight. It switches up to 10 A at 48 VDC. The occurrence of electric arcs is prevented by the special design and the use of state-of-the-art electronic components (semiconductors). As a result, the electronic DC pushbutton has a significantly longer service life (more than 1 million switching cycles) and is more reliable than any comparable electromechanical alternative.

UST 1206 - New Up To 35 A
In 2008, Schurter launched the first SMT chip fuse in the 1206 format: the UST 1206. Since then, this particularly compact and powerful fuse has enjoyed great popularity. In response to a number of customer requests, SCHURTER is expanding its product portfolio with even more powerful versions of the UST 1206 with rated currents of up to 35 A.
The Schurter UST 1206 is a chip fuse for surface mounting with a “slow-blow” characteristic. This means that it has a high melting integral I2t, thanks to which the fuse does not trip immediately at inrush current peaks higher than the rated current. This is of great importance in many industrial applications (e.g. motors, power converters).
UL 248-14 Characteristic
The UST 1206 was designed for UL 248-14 characteristics. With such fuse-links, the rated current corresponds to the current that interrupts the current flow after several hours. The maximum current that may flow continuously without the fuse-link tripping is around 70 % of the rated current.
New Variants up to 35 A
Previous versions of the UST 1206 had a maximum rated current of 25 A. This range will be increased to 30 A and 35 A with two further variants. The rated voltage is 32 VAC and 63 VDC respectively. The fuse can be operated from -55 °C to +90 °C.
Application Areas
The Schurter UST 1206 is ideally suited for all applications in secondary overcurrent protection where the current requirement is particularly high even at low voltages.

The first plant-based Schurter connectors were launched in July last year. Now Schurter is following suit and significantly expanding its portfolio of “Green Line” connectors. Because wherever you can reduce your CO2 footprint without compromising on quality, you really should do so.
As with the launch of the first series of Green Line products, Schurter remains true to its policy of offering a version with plant-based housings for products that are already established on the market. This approach offers customers of these products the great advantage that no redesigns or recertifications are
necessary when replacing the old connectors based on fossil raw materials. The Schurter Green Line is therefore a 1:1 replacement with all certifications.
New to the Green Line
The steadily expanding Schurter Green Line now includes the 4797 appliance outlet, the 4798 and 6080 appliance inlets and the 4782 rewireable connector.
Bio-Based Plastics
The environmentally friendly alternative to the fossil-based plastics commonly used today are plastics made from plant-based raw materials. Plant-based raw materials have a neutral CO2 footprint over their entire life cycle, which leads to a significant reduction in overall CO2 emissions. In addition, bio-based plastics often have a lower density than fossil-based plastics, which leads to lower material consumption.
Quality
In addition to CO₂ reduction, the bioplastic is also impressive in terms of safety and quality. It meets all technical and visual requirements. Products made from bioplastics impress with the same performance and service life as those made from fossil, crude oil-based plastic. Of course with all the international approvals needed.

The 4799 rewireable IEC connector from Schurter is the first of its kind: it combines a rewireable C19 connector with the proven V-Lock cord retention system.
Fast reaction time is an important factor in opening a new market for a device. Rewirable connectors are particularly flexible and especially suitable for small series of mains cables to enable exactly this. These connectors give you the freedom to choose the right cable with a country-specific plug.
Applications for a Safe Connection (V-Lock)
With electrical appliances that are moved or vibrate during operation, there is a risk of the power cable being unintentionally pulled out of the appliance, resulting in a power failure. Therefore, cord retention systems such as the one on the 4799 are a cost-effective solution to a potentially expensive problem. Cord retention systems are typically required for applications in the field of medical analysis, diagnostic or laboratory equipment, portable instruments, professional audio/video applications or equipment in the food industry.
Halogen-Free Design
Type 4799 from Schurter does not use halogens for the bushing or any other plastic components.
Approvals and Certifications
The 4799 connector has all approvals for the European, Chinese and North American markets. It is certified in accordance with the IEC/UL/CCC 60320 standard.

DKCV-1 Current-Compensated Chokes for Vertical PCB Mounting
Schurter is launching a new, vertically mountable choke family for PCBs with very high inductances. The DKCV-1 current-compensated chokes are designed for currents from 0.5 to 10 A. Thanks to their nanocrystalline cores, the new chokes have very high inductances with particularly compact dimensions.
Powerful applications in the energy sector are becoming increasingly compact. This compact design combined with high energy efficiency leads to an increase in electromagnetic interference in modern electronic devices. Powerful filter elements are required to suppress this interference. Due to the compact dimensions, the integration of the filter elements on printed circuit boards is an ideal solution. The new DKCV-1 choke series is particularly suitable for applications that require high attenuation.
High Performance in a Compact Design
The nanocrystalline cores enable very high currents with extremely compact dimensions. Thanks to the vertical choke arrangement, they also require very little space on the PCB. All variants of the DKCV-1 family have the same footprint on the PCB.
Applications
The new chokes are ideal for demanding applications that require high inductance with compact dimensions. These include switching power supplies, industrial, medical, laboratory and test equipment. The chokes are suitable for currents up to 10 A and voltages up to 300 VAC or 450 VDC and have ENEC,
cUR and UR approvals. For higher power applications, the DKIV-1 series of chokes is available with rated currents up to 50A.

Plugging Aid and Protection Cover for all OGN Fuse Holders
For the Schurter OGN fuse holder, which is available in THT, SMT and THR technology, Schurter offers a variety of different covers in addition to a dedicated plugging aid. Schurter launches the OGN Adapter for easy mounting and removal of fuses and at the same time serves as a cover for the OGN fuse holders.
The currently available OGN plugging aid is a very useful tool for placing 5x20 fuses into all types of OGN fuse holder. It makes placing and replacing of fuses much easier, especially on densely packed PCBs.
It is often the case that the plugging aid remains in place together with the fuse, which means that the plugging aid also remains in the appliance during operation. However, this is not permitted for safety reasons. With a rated power consumption of 2.5W/10 A, the plugging aid is endangered to overheat. Schurter is now taking this into account with the launch of the new OGN Adapter. At 4W/16A, it is significantly more heat-resistant and has also been tested for glow-wire resistance. It can therefore remain in the device during operation with a clear conscience (VDE approval) and serve as a cover.
The new OGN Adapter can therefore replace two products at once: the cover and the plugging aid. The OGN Adapter is going to replace the existing OGN plugging aids. They are not recommended anymore for new designs and will fall out of the product range soon.

Schurter has a long tradition with circuit breakers. In addition to their thermal release (bimetal), the classic TA35 and TA36 are now optionally equipped with an additional magnetic module, which promises reliable protection within milliseconds in the event of very high overcurrent (short circuit).
Thermal Circuit Breakers
Circuit breakers are usually designed according to the thermal principle with a bimetal. If a defined temperature is exceeded due to overcurrent, the electric circuit is interrupted. Once the bimetal cooled down, the appliance is ready for use again. However, if a short circuit occurs, the bimetal cannot react fast enough. For this reason, thermal circuit breakers are usually combined with a fuse.
Additional Magnetic Module
Schurter is now upgrading its 2-pole classic TA35 and TA36 models with an additional, optional magnetic module. From now on, no additional fuse is required when using a thermal-magnetic type. Depending on the application, the magnetic modules are available either with a slow or a fast acting characteristic.
Both models are designed for snap-in mounting and with finely graduated rated currents. A variety of colours and lighting options make the designer's choice easier. The Schurter TA35 has a more classic style, while its TA36 counterpart comes in a more modern design. A circuit breaker with a short circuit protection is mainly meant for applications, where a full protection on the primary side is required.
