MF-RG600-AP

Overview

The MF-RG600-AP is a surface-mount PTC resettable fuse manufactured by Bourns Inc. It belongs to the MF-LR series and features a rectangular package with dual flat tin/silver terminations. The component is lead-free, RoHS compliant, and operates within standard ambient temperature ranges. Designed for overcurrent protection in compact electronic assemblies, it offers low resistance characteristics suitable for sensitive circuit applications requiring reliable thermal response.

Feature Summary

• Provides automatic circuit recovery after fault clearance without manual replacement
• Surface mount construction enables automated assembly on printed circuit boards
• Low initial resistance minimizes power loss during normal operation

Applications

• Portable consumer electronics battery protection
• USB peripheral interface circuits
• Laptop and tablet internal bus protection

Procurement Notes

Verify the specific suffix AP against official Bourns documentation to confirm packaging configuration. Ensure the part number matches the required hold current and trip current specifications for your design. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component based on its surface mount footprint compatibility and thermal performance requirements. Evaluate the maximum operating voltage and trip time characteristics against the protected circuit's fault conditions. Ensure the PCB layout supports adequate heat dissipation for reliable resetting behavior under repeated fault scenarios.

Part Context

This device is part of Bourns' MF-LR family of polymeric positive temperature coefficient devices. These components are engineered for high-reliability overcurrent protection in space-constrained environments. The series utilizes proprietary polymer technology to balance fast tripping speeds with robust cycling endurance for long-term application stability.

Replacement Considerations

Consult official Bourns substitution guides for verified equivalents. Generic replacements may differ in trip time or holding current characteristics. Verify that any substitute maintains identical package dimensions and termination plating to ensure mechanical and electrical compatibility.
