High-Precision SMD0603R020SF Auto-Reset Fuse – Reliable Circuit Protection
Self-healing thermal fuse with ultra-low 0.02Ω resistance ensures minimal voltage drop and energy loss. Precision-engineered PPTC (Polymer Positive Temperature Coefficient) material guarantees rapid response to overcurrent while automatically resetting after fault clearance. 0603 compact SMD design (1.6mm x 0.8mm) saves PCB space, ideal for high-density electronics like IoT devices, wearables, and automotive control modules. Flame-retardant epoxy coating meets UL94 V-0 standards for extreme heat resistance. Perfect for USB-C ports, battery management systems, and industrial sensors. Bulk pricing available for OEM/ODM partners. Global stock, ready to ship.
