Overview
The Bourns MF-RHT700-2-14 is a radial leaded, high-temperature Polymeric Positive Temperature Coefficient (PPTC) resettable fuse from the MF-RHT series. Designed for PCB mounting, it features a hold current of 7 A and a trip current of 13 A at a maximum voltage of 16 V. The device exhibits a low resistance of 25 mΩ and offers a high interrupt rating of 100 A. It operates within a temperature range of -40°C to +125°C with a 5.1 mm lead spacing.
Feature Summary
- Provides automatic circuit protection through self-resetting thermal response mechanisms
- Engineered for reliable operation in elevated temperature environments up to 125°C
- Features radial leads for secure printed circuit board mounting applications
Applications
- High-temperature electronic circuit protection
- Overcurrent safeguarding in industrial equipment
- Power supply input protection
Procurement Notes
Verify the specific ordering suffix '-14' against your bill of materials, as it indicates reel packaging. Confirm that the 16 V maximum voltage rating aligns with your system's operating requirements. Ensure the 7 A hold current meets the continuous load demands without nuisance tripping during normal operation.
Selection Notes
Select this component when a radial PTC fuse is required for high-current applications exceeding standard surface-mount options. The 125°C maximum operating temperature distinguishes it from standard PPTC devices. Verify that the 100 A interrupt rating exceeds the prospective fault current available at the installation point to ensure safe disconnection capability.
Part Context
This part belongs to the MF-RHT series, which expands Bourns' portfolio of high-temperature resettable fuses. The series addresses the need for robust overcurrent protection in demanding thermal environments where standard polymeric fuses might fail or degrade prematurely.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official manufacturer resources for cross-reference data.
