Circuit Protection Electronics chip chip fuse fuse

SCHURTER UAI 1206 chip fuse delivers pulse withstand and temperature resistant capabilities, together with time-lag characteristics. The evolved overcurrent protection device is suitable for applications where durability and maximum reliability are required in the smallest possible footprint. Designed using firm’s ‘trace in air’ construction, device’s ability to resist current pulses smaller than the melting integral (I2t) is thereby increased exponentially. Product has practically no de-rating to the usual extent. Additionally, the unique design of the fuse body also dampens temperature fluctuations to a high degree. Designed to UL 248-14, device was originally developed specifically for automotive applications and comes in two versions with rated currents of 5.3A and 7.5A at 32Vdc.
