1210L050/30WR Description

Short technical summary and product information.

The Littelfuse 1210L050/30WR is a PolySwitch polymeric PTC resettable fuse from the 1210L series, designed for surface mount overcurrent protection in space-constrained applications. Its compact 1210 (3225 Metric) concave package makes it suitable for automated assembly.

 

This device offers a hold current of 500 mA and a trip current of 1.00 A. With a maximum voltage rating of 30 V and a maximum interrupt current of 40 A, it provides robust protection. Typical power dissipation is 0.60 W, and the time to trip at 8.00 A is 150 ms.

 

The resistance values are 0.220 Ω minimum initial (Rmin) and 0.900 Ω maximum post-trip (R1max). The operating temperature range spans -40°C to 85°C, covering most industrial and consumer environments.
