Overview
The MF-RHT900-AP-14 is a polymeric resettable fuse manufactured by Bourns Inc., designed for high-temperature circuit protection. It features a radial leaded package with a hold current of 9.0A and a trip current of 16.5A at a maximum voltage of 16V. The device supports a maximum fault current of 100A and has a time to trip of 10 seconds. It operates within a temperature range up to 125°C and is qualified under AEC-Q200 Rev-D standards for automotive applications.
Feature Summary
- Polymeric construction for reliable overcurrent protection
- Radial leaded package design for through-hole mounting
- Qualified for automotive environments via AEC-Q200 stress testing
Applications
- Automotive electronic circuits requiring AEC-Q200 compliance
- High-temperature industrial control systems
- Consumer electronics power input protection
Procurement Notes
Verify the specific suffix (e.g., -AP-14) against official Bourns documentation to ensure correct hold current, trip characteristics, and packaging configuration. Confirm that the component meets the required AEC-Q200 qualification level if used in automotive contexts. Cross-reference datasheet parameters such as thermal derating factors and maximum operating temperatures with system requirements before procurement.
Selection Notes
Select this component when a radial PTC fuse with a 9.0A hold current and 16V rating is required for high-temperature environments. Ensure the application can accommodate the 10-second trip time and 100A maximum fault current capability. Verify that the physical dimensions and lead spacing fit the PCB layout constraints.
Part Context
This part belongs to the MF-RHT series of high-temperature resettable fuses from Bourns. The series is characterized by its ability to operate in elevated temperature conditions and its compliance with automotive reliability standards. The specific model indicates a 9.0A rating and radial lead configuration.
Replacement Considerations
Direct substitutes include other Bourns MF-RHT series parts with matching electrical ratings, such as the MF-RHT900-0-14 or MF-RHT900-AP, provided they meet the same voltage, current, and temperature specifications.
