MF-USML650/6-2

Overview

The Bourns MF-USML650/6-2 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 footprint and low profile suitable for dense PCB layouts. The device functions as a current-limiting component that automatically resets after cooling down from a trip condition, eliminating the need for manual replacement. It provides reliable overcurrent protection in electronic assemblies where space constraints are critical.

Feature Summary

Surface-mount construction for automated assembly
Polymeric PPTC technology for automatic reset capability
Compact form factor optimized for high-density boards

Applications

Portable consumer electronics
Laptop and notebook computer peripherals
USB interface circuits

Procurement Notes

Verify the specific suffix codes against official Bourns documentation to ensure correct voltage and current ratings. Confirm RoHS compliance status with the manufacturer prior to procurement. Check for any recent lifecycle notices or obsolescence alerts. Ensure the selected variant matches the required hold and trip current specifications for the target application design.

Selection Notes

Select this component based on the required operating voltage and maximum trip current limits defined in the datasheet. Evaluate the physical dimensions to ensure compatibility with the printed circuit board copper pad layout. Consider the ambient operating temperature range to guarantee proper function without nuisance tripping during normal operation.

Part Context

This part is part of the Bourns USML series of miniature resettable fuses. The series is engineered for applications requiring small footprints and low profiles. It serves as an alternative to traditional fusible links in modern electronic devices where space efficiency and serviceability are prioritized.

Replacement Considerations

Consult official Bourns substitution guides for verified equivalents. Do not assume cross-compatibility with other manufacturers' PPTC devices without verifying electrical parameters and mechanical dimensions.
