MF-RHT1100-2

Overview

The Bourns MF-RHT1100-2 is a radial leaded polymer PTC resettable fuse from the Multifuse MF-RHT series. It features a maximum voltage of 16 V and a hold current of 11 A, with a trip current of 22 A. The device supports a maximum fault current of 100 A and has an initial resistance of 7.4 mOhms. It operates within a temperature range of -40°C to +125°C and holds AEC-Q200 qualification for automotive applications.

Feature Summary

• High-temperature capability up to 125°C for demanding environments
• AEC-Q200 qualified for automotive reliability standards
• Radial leaded package for through-hole PCB mounting

Applications

• Automotive electronics circuit protection
• Power supply input/output overcurrent protection
• Battery pack protection systems

Procurement Notes

Verify the specific suffix '-2' corresponds to the reel packaging format as indicated in distributor listings. Confirm that the AEC-Q200 qualification meets the specific automotive grade requirements for the target application. Ensure the 11 A hold current aligns with the system's normal operating load to prevent nuisance tripping during steady-state conditions.

Selection Notes

Select this component when high-temperature operation up to 125°C is required alongside standard 16 V system voltages. The 11 A hold current suits moderate-to-high current circuits needing resettable protection. Consider the radial leaded form factor for manual assembly or automated through-hole processes where surface mount alternatives are unsuitable.

Part Context

This part belongs to the MF-RHT series, designed specifically for high-temperature environments compared to standard PPTC fuses. It shares the Multifuse brand identity but distinguishes itself through extended thermal ratings and automotive certification, differentiating it from the lower-temperature MF-R or MF-RG series variants.
