Chipfuses: precise and low-loss


SCHURTER offers a wide range of high-quality chip fuses. These have been specially developed for precise and low-loss overcurrent protection in secondary circuits. Six different types in chip sizes from 0402 to 1206 guarantee compact and effective protection in the event of a fault.


The chip fuses from SCHURTER are available in many nominal current versions from 50 mA to 25 A with a nominal voltage of up to 125 VAC/VDC. Depending on the version and rated voltage, a breaking capacity of up to 600 A reached. These remarkably high values and the wide range of variants of these chip fuses enable a large number of applications. The chip fuses are particularly suitable for mobile and battery-operated devices in sensor technology and industrial electronics.

The chip fuses from SCHURTER stand out from comparable products due to their extremely precise tripping times and lowest power losses. Their solid construction also makes them particularly resistant to vibrations and pulse loads. Furthermore, the partially gold-plated SMD contacts have a positive influence on the wettability, storage time and contact quality of the chip fuses.


All chip fuses from SCHURTER have a cURus approval, the USI 1206 additionally and as the only chip fuse on the market also has a VDE approval. Since they are halogen-free and RoHS-compliant, the chip fuses from SCHURTER can also be used for lead-free soldering processes. SCHURTER offers all chip fuses in small, medium and large packaging units and impresses with very attractive prices, especially in the mass market.

Thermal Runaway

With a power semiconductor (e.g. MOSFET) the drain-source transmission resistance increases with rising temperatures, when connected, which results in an increasing loss of power in the barrier layer. If the elements are not sufficiently cooled - the high power density permits cooling - the power loss output in the form of heat can no longer be sufficiently dissipated, which also increases the transmission resistance.

This process escalates and ultimately leads to destruction of the component.

Properties and benefits
