Overview
The Bourns MF-RHT650-0-14 is a high-temperature polymeric positive temperature coefficient (PPTC) resettable fuse designed for overcurrent and overtemperature protection. It features a radial leaded package with a maximum voltage rating of 16V and a hold current of 6.5A. The device trips at 12A within 5.5 seconds and withstands up to 100A maximum current. Operating temperatures range from -55°C to +155°C, with a resistance between 11mΩ and 26mΩ.
Feature Summary
- Provides automatic circuit protection against overcurrent and overtemperature conditions
- High-temperature capability suitable for demanding thermal environments
- Radial leaded construction facilitates through-hole PCB mounting
Applications
- Automotive electronic circuits requiring AEC-Q100 compliance
- Industrial power supply protection systems
- Consumer electronics requiring thermal safety standards
Procurement Notes
Verify the specific suffix '0-14' against official Bourns documentation to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required axial or radial lead configuration and ambient temperature ratings for the target application environment.
Selection Notes
Select this component when applications require a 6.5A hold current and 16V rating in high-temperature scenarios. Consider the 12A trip threshold and 5.5-second response time for circuit coordination. Verify that the radial lead spacing and physical dimensions fit the printed circuit board layout constraints.
Part Context
This part belongs to the Bourns MF-RHT series of high-temperature PTC resettable fuses. The series is engineered for robust performance in automotive and industrial sectors, offering reliable protection where standard polymer fuses may fail due to elevated ambient temperatures.
Replacement Considerations
Cross-reference with MF-RHT650-AP or MF-RHT650-2-14 for alternative packaging options such as ammo pack or bulk. Confirm that electrical parameters including hold current, trip current, and voltage ratings remain identical before substitution.
