Overview
The Bourns MF-RHT1300-AP is a PTC resettable fuse from the Multifuse series, designed for overcurrent protection in high-temperature environments. It features a hold current of 13 A and a maximum voltage rating of 16 V. The device has a typical resistance of 2.5 mOhms and a trip current of 24 A, with a maximum rated current of 100 A. It operates within a temperature range of -40°C to +125°C and carries AEC-Q200 qualification. The component utilizes a radial leaded package with a 5.1 mm lead spacing.
Feature Summary
- Provides automatic circuit recovery after fault clearance without manual replacement
- Engineered for reliable operation in high-temperature automotive applications
- Radial leaded construction facilitates direct PCB mounting
Applications
- Automotive electronic module protection
- High-temperature circuit surge suppression
- AEC-Q200 qualified vehicle subsystems
Procurement Notes
Verify the specific suffix (e.g., AP) against official Bourns documentation to confirm packaging type and exact electrical tolerances. Ensure the selected variant meets the required AEC-Q200 qualification standards for your application. Cross-reference the datasheet for precise dimensional constraints and thermal derating curves before finalizing procurement specifications.
Selection Notes
Select this component when a 13 A hold current and 16 V rating are required for high-temperature protection. Consider the 2.5 mOhms resistance for power loss calculations. Verify that the radial lead spacing matches the PCB layout. Confirm AEC-Q200 compliance if used in automotive contexts. Compare with lower or higher current variants in the MF-RHT series if system requirements differ.
Part Context
The MF-RHT1300-AP belongs to the Bourns Multifuse MF-RHT series, which specializes in high-temperature PTC resettable fuses. This series is distinct from standard polymeric devices due to its enhanced thermal stability and automotive-grade qualification. The part serves as a reusable alternative to traditional one-time fuses in demanding electronic environments.
Replacement Considerations
Direct substitutes include other MF-RHT series parts with similar current ratings, such as MF-RHT1100-2 or MF-RHT900-2, provided voltage and temperature ratings align. Verify lead spacing and package dimensions match the existing footprint before substitution.
