MF-MSMF150-2

Ptc Resettable Fuses Overview

The Bourns MF-MSMF150-2 is a surface-mount polymer positive temperature coefficient (PPTC) resettable fuse from the MF-MSMF series. It features a 1.5 A hold current, 3 A trip current, and a maximum voltage rating of 6 VDC. The device offers a maximum fault current rating of 100 A and an initial resistance of 120 mΩ. Housed in an 1812 (4532 metric) package, it operates within a temperature range of -40°C to +85°C. This component is AEC-Q100 qualified for automotive applications.

Ptc Resettable Fuses Feature Summary

Provides overcurrent protection through automatic resistance increase during fault conditions
Designed for high-reliability automotive circuit environments
Enables compact surface-mount integration for space-constrained layouts

Ptc Resettable Fuses Applications

Automotive electronic circuit protection
Battery management systems
Portable electronic device power lines

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix and voltage rating against the target circuit requirements. Confirm that the 6 VDC maximum voltage aligns with the system's operating parameters. Ensure the 1.5 A hold current meets the normal operational load without nuisance tripping. Check for AEC-Q100 qualification if the application mandates automotive grade standards.

Ptc Resettable Fuses Selection Notes

Select this component when low voltage operation around 6 VDC is required alongside a 1.5 A continuous current capacity. The 1812 footprint suits designs needing moderate current handling in a small area. Consider the 120 mΩ resistance impact on power loss. Verify that the 100 A max fault current capability matches the potential short-circuit levels in the protected circuit.

Ptc Resettable Fuses Part Context

This part belongs to the MF-MSMF series of high-density SMD PPTC devices. It shares the family's polymer construction but differs in electrical ratings from other variants like the MF-SM150/33-2 or MF-MSMF150/24X-2. The series is engineered for robust performance in demanding environments, specifically targeting automotive and industrial sectors requiring reliable resettable protection.
