Overview
The Bourns MF-RHT700-2-14 is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse from the MF-RHT series. It features a hold current of 7 A and a trip current of 13 A at a maximum voltage of 16 VDC. The device has a maximum fault current rating of 100 A and a typical resistance of 25 mOhms. It operates within a temperature range of -40°C to +125°C with a lead spacing of 5.1 mm.
Feature Summary
- Provides automatic circuit protection through self-resetting functionality upon cooling after fault conditions.
- Designed for high-temperature environments with an operational limit up to +125°C.
- Utilizes radial leaded construction for direct PCB mounting applications.
Applications
- Overcurrent protection in automotive electronic circuits
- Protection for industrial control systems
- Power supply input stages
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number MF-RHT700-2-14 with official Bourns documentation. Confirm that the received items match the specified 7 A hold current and 16 VDC rating. Ensure the package type corresponds to radial leads with 5.1 mm spacing. Check for any specific handling requirements related to high-temperature PPTC materials during storage and assembly.
Selection Notes
Select this component when a resettable overcurrent protector is required for low-voltage DC circuits operating up to 16 V. The 7 A hold current suits applications needing moderate continuous current capacity. The high-temperature rating makes it suitable for enclosed or high-heat environments where standard fuses might fail prematurely. Ensure the expected fault current does not exceed the 100 A maximum interrupting rating.
Part Context
This part belongs to the Bourns MF-RHT series, which specializes in high-temperature PPTC resettable fuses. The series is engineered to provide reliable protection in demanding thermal conditions. The MF-RHT designation indicates specific material properties optimized for stability and performance at elevated temperatures compared to standard PPTC devices.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before considering alternative manufacturers or series.
