The C3157165 SCHURTER ceramic tube fuse provides reliable overcurrent protection for low-voltage circuits with a 1.5kA interrupt rating and operational range of -55℃ to +125℃. Designed for disposable applications in consumer electronics and medical devices, it features 800mA current rating and 250V AC/300V DC voltage ratings. Proper soldering at 300-350℃ with 60-90s hold time ensures reliable assembly. Engineers should maintain 3mm thermal clearance during layout and verify pad dimensions. While offering high reliability and ROHS compliance, its 300V DC limit and higher cost represent key limitations for industrial applications.
