MF-USML175/12-2

Overview

The Bourns MF-USML175/12-2 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It belongs to the USML series, characterized by its compact form factor suitable for space-constrained applications. The component functions as a current-limiting device that automatically resets after cooling down from a trip condition, providing reliable overcurrent protection without requiring manual replacement.

Feature Summary

Surface-mount construction for automated assembly
Self-resetting action upon cooling
Compact footprint for dense PCB layouts

Applications

Portable electronic devices
Consumer electronics
Telecommunications equipment

Procurement Notes

Verify the specific suffix codes against the official datasheet to ensure correct voltage and current ratings. Confirm RoHS compliance status and packaging details with the authorized distributor prior to ordering. Ensure the selected variant matches the required hold and trip currents for the target application circuit.

Selection Notes

Select this component based on the required operating voltage and maximum trip current specifications. Evaluate the physical size constraints of the printed circuit board layout to ensure compatibility with the surface-mount package dimensions. Consider the ambient operating temperature range to guarantee proper functionality and reliability under expected environmental conditions.

Part Context

This part is part of Bourns' USML series of surface-mount PPTC devices. The series offers various hold and trip current options within a standardized small outline package. These components are engineered to replace traditional fuses in applications where automatic recovery is beneficial.

Replacement Considerations

Consult the official Bourns substitution guide or datasheet for verified equivalent parts. Do not assume cross-compatibility with other manufacturers' PPTC devices without verifying electrical parameters and physical dimensions.
