RUEF300 Description

Short technical summary and product information.

The Littelfuse RUEF300AP is a resettable fuse belonging to the PTC (Positive Temperature Coefficient) family, designed for reliable circuit protection applications. This component offers a hold current of 3A and a trip current of 6A, with a maximum voltage rating of 30VDC.

 

Engineered for robust performance, the RUEF300AP has a maximum current rating of 100A and a typical resistance of 80 mOhms. It operates effectively within a temperature range of -40°C to +85°C.

 

The fuse is designed for PCB mounting with radial termination and a lead spacing of 5.8 mm. It is supplied in an Ammo Pack package, suitable for automated assembly processes. This resettable fuse provides a self-resetting protection mechanism, making it ideal for applications requiring overcurrent protection that can recover after the fault condition is removed.
