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.
