MF-USMF110-2

Overview

The Bourns MF-USMF110-2 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the MF-USMF series. It features a hold current of 1.1 A and a trip current of 2.2 A, with a maximum voltage rating of 6 VDC. The device offers a maximum fault current rating of 40 A and an initial resistance of 210 mOhms. Housed in a 1210 (3225 metric) package, it operates within a temperature range of -40°C to +85°C. This component is qualified under the AEC-Q100 standard for automotive applications.

Feature Summary

Provides overcurrent protection through automatic reset functionality upon cooling after tripping
Designed for surface mount technology integration on printed circuit boards
Complies with AEC-Q100 qualification standards for automotive electronic reliability

Applications

Automotive electronics circuits requiring AEC-Q100 compliance
Low-voltage DC power line protection up to 6 VDC
Consumer electronics port protection

Procurement Notes

Verify the specific ordering suffix matches the required package style and tape/reel configuration. Confirm that the AEC-Q100 qualification aligns with your automotive supply chain requirements. Ensure the 1210 footprint dimensions are compatible with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a compact 1210 form factor is required for low-voltage bus protection. The 1.1 A hold current suits moderate load applications. Consider the 6 VDC limit for system voltage compatibility. The AEC-Q100 certification makes it suitable for automotive environments where high reliability is mandated.
