MF-USML600/6-2

Overview

The Bourns MF-USML600/6-2 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It features a 1210 (3225 Metric) package and operates at a maximum voltage of 6 VDC. The device has a hold current of 6 A and a trip current of 12 A, with a maximum current rating of 50 A. It dissipates up to 1.2 W and typically trips within 2 seconds under overload conditions, exhibiting a resistance of approximately 0.001 Ohms.

Feature Summary

Polymeric PPTC technology provides automatic reset functionality after fault clearance
Surface mount construction in a compact 1210 package for automated assembly
High current handling capability suitable for protecting low-voltage power lines

Applications

Overcurrent protection for portable electronic devices
Protection circuits in automotive electronics systems
Power supply input protection for industrial control equipment

Procurement Notes

Verify the specific ordering suffix matches the required hold and trip currents. Confirm RoHS compliance status if restricted substances are prohibited. Ensure the 1210 package dimensions align with the PCB footprint design. Check manufacturer lead times as they may extend significantly due to production schedules.

Selection Notes

Select this component when a low-voltage, high-current resettable fuse is required. The 6V rating limits its use to low-voltage DC applications only. Consider the 6A hold current against normal operating loads to prevent nuisance tripping. Evaluate the thermal environment to ensure proper derating is applied for reliable operation.

Part Context

This part belongs to the Bourns MF-USML series of miniature resettable fuses. The series is characterized by small form factors and high current ratings relative to their size. These components serve as alternatives to traditional one-time fuses in space-constrained designs requiring user-resettable protection.

Replacement Considerations

The MF-USML600-2 is listed as an equivalent or substitute part number. Verify that the electrical parameters, specifically the 6V and 6A ratings, match the original design requirements before substitution.
