MF-RHS1200-0

Overview

The Bourns MF-RHS1200-0 is a radial leaded polymer PTC resettable fuse from the Multifuse MF-RHS series. It provides overcurrent protection with a hold current of 12 A and a trip current of 24 A at maximum voltage of 16 V DC. The device features a minimum initial resistance of 3 mΩ and a maximum post-trip resistance of 7 mΩ, with a maximum fault current rating of 100 A. It operates within a temperature range of -40°C to +125°C and utilizes a through-hole mounting style.

Feature Summary

• Polymer PTC technology for high-temperature circuit protection
• Radial leaded package for through-hole PCB mounting
• Self-resetting function eliminates manual replacement after fault clearance

Applications

• Overcurrent protection in industrial equipment
• Surge protection for communication systems
• Circuit safeguarding in consumer electronics

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number MF-RHS1200-0 with official Bourns documentation. Confirm that the specific ordering suffix matches the required radial leaded configuration and that RoHS compliance status aligns with project requirements before finalizing procurement orders.

Selection Notes

Select this component when applications require high hold currents around 12 A with low impedance characteristics. Ensure the operating environment does not exceed the +125°C maximum temperature limit. Verify that the system voltage remains within the 16 V DC maximum rating to ensure proper tripping behavior and safety certification compliance.

Part Context

This component belongs to the Multifuse MF-RHS series, designed for high-temperature environments up to 125°C. The series offers robust protection against short circuits and overcurrent conditions in space-constrained layouts compared to traditional fuses, providing reliable performance in demanding electronic assemblies.

Replacement Considerations

Consult official Bourns substitution guides for compatible alternatives within the MF-RHS family. Verify that any substitute maintains identical hold current, voltage rating, and physical dimensions to ensure board compatibility and electrical performance equivalence.
