MF-RHT650-0

Overview

The Bourns MF-RHT650-0 is a high-temperature PTC resettable fuse from the Multifuse MF-RHT series, designed for radial leaded PCB mounting. It features a hold current of 6.5 A and a trip current of 12 A at a maximum voltage of 16 V. The device offers a maximum interrupt rating of 100 A and an initial resistance of 11 mΩ, rising to a maximum post-trip resistance of 26 mΩ. It operates within a temperature range of -40°C to +125°C and meets AEC-Q200 automotive qualification standards.

Feature Summary

• High-temperature polymer construction suitable for demanding thermal environments
• Radial leaded through-hole package for standard PCB integration
• Automotive-grade reliability certified under AEC-Q200 standards

Applications

• Automotive electronic circuit protection
• Industrial instrumentation overcurrent safeguarding
• Power conversion system component protection

Procurement Notes

Verify the specific suffix against official Bourns documentation to confirm packaging configuration, as variants such as MF-RHT650-2 utilize reel packaging while others may use ammo packs or bulk. Confirm that the AEC-Q200 qualification status aligns with project requirements before finalizing procurement orders.

Selection Notes

Select this component when a 6.5 A hold current and 16 V maximum voltage are required for radial mounting applications. Ensure the design accommodates the specified 12 A trip threshold and verify that the operating environment remains within the -40°C to +125°C range for optimal performance.

Part Context

This part belongs to the Bourns Multifuse MF-RHT series, which specializes in high-temperature PPTC resettable fuses. The series provides robust circuit protection solutions for automotive and industrial sectors where standard polymeric devices may fail due to elevated thermal conditions.

Replacement Considerations

MF-RHT650-2 serves as a verified substitute within the same series, offering identical electrical characteristics but differing in packaging format.
