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.
