MF-RHT300-2

Overview

The Bourns MF-RHT300-2 is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse designed for high-temperature applications. It features a holding current of 3 A and a trip current of 6 A, operating within a maximum voltage of 16 VDC. The device has a minimum operating temperature of -40°C and a maximum of +125°C, with a maximum rated current of 100 A and a resistance of 79 mΩ. It meets the AEC-Q200 qualification standard and utilizes a 5.1 mm lead spacing.

Feature Summary

Provides overcurrent protection through automatic reset functionality upon cooling after tripping
Engineered for reliable operation in high-temperature environments up to 125°C
Complies with automotive industry reliability standards including AEC-Q200 qualification

Applications

Automotive electronic circuit protection
High-temperature industrial equipment safeguarding
Consumer electronics power line protection

Procurement Notes
