Ptc Resettable Fuses Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 6.5 A hold current and 16 V rating. Confirm AEC-Q200 qualification status if automotive application is intended. Ensure the radial leaded package dimensions and 5.1 mm lead spacing fit the target PCB layout. Check RoHS compliance documentation for regulatory requirements.

Ptc Resettable Fuses Selection Notes

Select this component when a radial leaded PPTC fuse is required for circuits operating up to 16 VDC. The 6.5 A hold current suits applications needing moderate overcurrent protection. Consider the 125°C operating temperature limit for thermal management. Compare against other MF-RHT series variants if different current ratings or package styles are needed.

Ptc Resettable Fuses Part Context

This device belongs to the Bourns Multifuse RHT series, designed for high-temperature polymer PTC applications. The series provides cost-effective protection against short circuits and overcurrent faults. It serves as an alternative to traditional fuses by offering resettable functionality without manual replacement after a fault event.

Ptc Resettable Fuses Replacement Considerations

MF-RHT650-0: Same electrical specifications but potentially different packaging or minor parameter tolerances; verify datasheet details before substitution.
