SMD, Thermal sensitive Fuse, USN 1206, 32 VDC

SCHURTER’s USN 1206 chip fuse offers temperature-sensitivity suitable for both overcurrent protection and protection against excessive ambient temperatures. It is also designed to protect power semiconductors in automotive applications against over-temperature.  The fuse has a current-time characteristic which shifts as a function of the ambient temperature.  As a result, a specific trigger at a certain threshold value can be achieved with increasing temperature. The 12 A current rated USN 1206 has high I2t values at 32 VDC and a slow blowing characteristic. It has a breaking capacity of 80 A at 32 VDC and 170 A at 16 VDC with an operating temperature range of a -40 degrees C to a +125 degrees C. The USN 1206 meets the AEC-Q200 standard making it suitable for automotive applications. Qualification is according to each unique customer requirement on request.
