MF-USML300/6-2

Overview

The MF-USML300/6-2 is a polymeric PTC resettable fuse manufactured by Bourns Inc. It features a surface mount package in the 1210 (3225 Metric) concave form factor. The device has a rated voltage of 6V and a hold current of 3A. It offers a high trip current capability and a maximum post-trip resistance of 20mOhm. The component operates within a temperature range of -40°C to 85°C and includes a maximum thickness specification of 1.40mm.

Feature Summary

Polymeric construction for reliable circuit protection
Surface mount design suitable for automated assembly
Concave package profile for low-profile integration

Applications

Portable electronic devices requiring overcurrent protection
Consumer electronics with limited board space
Battery-powered equipment circuits

Procurement Notes

Verify the specific suffix '6-2' against official Bourns documentation to confirm the exact package variant and electrical ratings. Ensure compatibility with the target PCB footprint, as the 1210 concave form factor requires precise soldering parameters. Cross-reference the hold current and trip current specifications with the system's operational requirements to prevent nuisance tripping or inadequate protection.

Selection Notes

Select this component when a low-voltage, high-current surface mount resettable fuse is required. The 1210 package size provides a balance between current handling capacity and board space efficiency. Consider the 6V rating limit and the 3A hold current when designing circuits that operate near these thresholds. Verify thermal management needs due to the self-heating characteristics inherent in PTC devices.

Part Context

This part belongs to the Bourns MF-USML series of polymeric PTC resettable fuses. These components are designed for circuit protection in applications where traditional fuses are impractical due to size or replacement constraints. The series offers various current ratings and package options to suit different electronic designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult Bourns official resources for direct replacements or cross-references.
