Littelfuse 0.2 A Resettable Fuse 30V DC Surface Mount Overcurrent Protection 1210L020WR

The Littelfuse 1210L020WR is a resettable polyfuse designed for overcurrent protection in electronic circuits operating at 30V DC with a hold current rating of 0.2 A and a maximum current rating of 10 A. It features surface mount technology and is housed in the compact 1210L series package, measuring 3.43 mm in length, 2.8 mm in width, and 1 mm in height, with tin-plated copper terminals.

This device rapidly transitions from a low resistance state to a high resistance state within 0.02 seconds under fault conditions to protect sensitive electronics from damage. Once the fault is cleared and power is removed, the fuse automatically resets, enabling maintenance-free circuit protection for thousands of cycles.

The fuse supports a power dissipation of 0.6 W and operates reliably within a temperature range of -40°C to 85°C. Its resistance varies between 0.8 Ω minimum and 5 Ω maximum, making it suitable for compact and sensitive electronic applications.

Common industrial applications for the 1210L020WR resettable fuse include security systems, medical and automotive equipment, power supplies, transformers, instrumentation, and telecommunications where space constraints demand surface mount components.

This product is packaged on a reel for automated assembly and complies with RoHS environmental standards. The 1210L series is well-suited for industrial, laboratory, manufacturing, and commercial electronics protection.

This resettable fuse uses surface mount technology to save space on PCBs. It quickly trips in 0.02 seconds during overcurrent conditions to protect circuits. The fuse automatically resets after power removal and fault clearance.

Compact 1210 package size and tin-plated copper terminals ensure easy mounting and reliable connections. Suitable for applications in security systems, power supplies, automotive, medical equipment, and telecommunications.

Provides maintenance-free protection for thousands of cycles without fuse replacement. Certified RoHS compliant for environmental safety. Explore more Resettable Fuses and circuit protection products at EnvMart for your industrial and electrical needs.
