Overview
The Bourns MF-RHT800-AP is a radial leaded, high-temperature polymeric positive temperature coefficient (PPTC) resettable fuse from the MF-RHT series. Designed for PCB mounting, this component provides circuit protection with a holding current of 8 A and a maximum voltage rating of 16 V. It features a low resistance of 8 mΩ and operates within a temperature range of -40°C to +125°C. The device is qualified under the AEC-Q200 standard, ensuring reliability in demanding environments.
Feature Summary
- High-temperature stability for reliable operation in elevated thermal conditions
- AEC-Q200 qualification for automotive application compliance
- Radial leaded package design for direct PCB integration
Applications
- Automotive electronic circuits requiring AEC-Q200 compliance
- High-temperature industrial instrumentation protection
- Consumer electronics power input safeguarding
Procurement Notes
Verify the specific suffix AP against official Bourns documentation to confirm exact packaging or tape-and-reel specifications. Ensure the selected variant matches the required axial or radial lead configuration for your PCB layout. Cross-reference the datasheet for precise reflow soldering profiles and thermal handling guidelines during assembly.
Selection Notes
Select this component when an 8 A holding current and 16 V maximum voltage are required for overcurrent protection. Consider the MF-RHT series for applications necessitating high-temperature resilience up to 125°C. Verify that the 8 mΩ resistance aligns with your system's power loss constraints and that AEC-Q200 certification is mandatory for the target market.
Part Context
This part belongs to the MF-RHT series of resettable fuses, which are engineered for robust performance in harsh environments. The series emphasizes high-temperature capability and automotive-grade reliability. Components in this family typically offer rapid response times and durable cycling characteristics suitable for repeated fault conditions without permanent degradation.
Replacement Considerations
Consult the official Bourns replacement guide for equivalent PPTC devices with matching 8 A and 16 V ratings. Verify that any substitute maintains AEC-Q200 qualification and similar thermal operating ranges. Ensure physical dimensions and lead spacing are compatible with existing PCB footprints before substitution.
