SCHURTER Chip Fuses

SCHURTER Chip Fuses are available in six distinct chip sizes ranging from 0402 to 1206, ensuring efficient and small-sized protection. They are specifically designed for accurate and low-loss overcurrent protection in secondary circuits. These chip fuses are offered with nominal voltages of up to 125V AC/DC and nominal currents ranging from 50mA to 25A and depending on the version and rated voltage, they can reach a breaking capacity of up to 600A. The robust structure of the chip fuses from SCHURTER makes them resistant to vibrations and pulse loads. They also have the lowest power losses, incredibly precise tripping times, and precise features.

Chip fuses from the SCHURTER are accessible in small, medium, and large package units and are halogen-free, cURus-certified, and RoHS-compliant. These chip fuses find applications in lead-free soldering processes, mobile and battery-operated devices in sensor technology, and industrial electronics.
