1210L175WR Description

Short technical summary and product information.

The Littelfuse 1210L175WR is a polymeric PTC resettable fuse from the 1210L series, designed for surface mount overcurrent protection in space-constrained applications. It offers a hold current of 1.75 A at 20°C still air and a trip current of 3.50 A. The device is rated for a maximum voltage of 6 V and can handle up to 100 A fault current. Typical power dissipation in the tripped state is 0.80 W.

 

Electrical characteristics include an initial minimum resistance of 20 mΩ and a maximum post-trip resistance of 80 mΩ. The time to trip is 600 ms at 8 A. The operating temperature range is -40°C to 85°C. The component is packaged in a 1210 (3225 metric) concave case and is RoHS, lead-free, and halogen-free compliant.

 

This resettable fuse provides reliable overcurrent protection without the need for replacement after a fault event, making it suitable for applications where resettability and compact size are critical. The surface mount package enables automated assembly and is ideal for high-volume production.
