MF-RG700-2

Overview

The Bourns MF-RG700-2 is a high-density PPTC resettable fuse from the Multifuse MF-RG series, designed for PCB mounting with radial termination. It features a hold current of 7 A and a trip current of 11.9 A, operating at a maximum voltage of 16 V. The device offers a maximum fault current rating of 100 A and maintains a low resistance of 13 mOhms. It functions within a temperature range of -40°C to +85°C, with a lead spacing of 5.1 mm and a height of 19.7 mm.

Feature Summary

• Provides overcurrent protection through automatic resetting capabilities upon cooling after tripping.
• High-density design allows for compact circuit board layouts while maintaining robust electrical performance.
• Radial leaded construction facilitates standard through-hole PCB mounting processes.

Applications

• Consumer electronics power input protection
• Battery pack circuit safeguarding
• Peripheral interface overcurrent limiting

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number MF-RG700-2 with official Bourns documentation. Confirm that the specific reel packaging matches the required quantity increments. Ensure the RoHS compliance status aligns with project regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a 16 V system requires a 7 A hold current with high surge tolerance. The radial package suits manual or automated insertion where space permits. Evaluate thermal derating curves to ensure reliable operation within the specified -40°C to +85°C environment without exceeding power dissipation limits.

Part Context

This part belongs to the Multifuse MF-RG series, characterized by high-current density and rapid response times. It serves as a reusable alternative to traditional fusible links in low-voltage applications. The series emphasizes compactness and reliability for protecting sensitive downstream components against accidental overloads.

Replacement Considerations

Consult official substitution guides for equivalent ratings. Verify that any alternative maintains identical voltage, hold current, and physical dimensions to ensure compatibility with existing PCB footprints and thermal profiles.

FAQ
