Overview
The MF-RHT900-2-14 is a high-temperature polymeric resettable fuse from the Bourns Multifuse MF-RHT series. It features a radial leaded package designed for PCB mounting. Key electrical parameters include a hold current of 9 A, a trip current of 16.5 A, and a maximum voltage rating of 16 V. The device exhibits a low resistance of 7.4 mOhms and can withstand a maximum fault current of 100 A. It operates within a temperature range of -40°C to +125°C and holds AEC-Q200 qualification for automotive reliability.
Feature Summary
- Provides overcurrent and overtemperature protection through automatic circuit interruption upon thermal activation.
- Features a robust radial leaded construction suitable for through-hole PCB mounting applications.
- Complies with AEC-Q200 standards to ensure reliability in demanding automotive environments.
Applications
- Automotive electronic circuit protection
- High-temperature power supply input stages
- Sensitive electronics requiring thermal overload safeguarding
Procurement Notes
Verify the specific suffix '-14' against official Bourns documentation to confirm tape-and-reel packaging details. Ensure the selected component matches the required 16V maximum voltage and 9A hold current specifications for the target application. Confirm AEC-Q200 compliance requirements are met by the manufacturer's latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when designing circuits that require resettable protection under high-temperature conditions up to 125°C. The 16V rating limits its use to low-voltage systems. Consider the 100A maximum fault current capability for short-duration surge events. Verify that the radial lead spacing aligns with the printed circuit board layout constraints.
Part Context
This part belongs to the MF-RHT series of high-temperature PTC resettable fuses manufactured by Bourns Inc. The series is engineered for automotive and industrial applications where standard components may fail due to elevated ambient temperatures. The product falls under the category of polymeric resettable fuses, offering a reusable alternative to traditional one-time fusible links.
Replacement Considerations
Consult official Bourns substitution guides for compatible alternatives. Generic PTC fuses may not match the specific AEC-Q200 qualification or high-temperature performance characteristics required for direct replacement in certified automotive assemblies.
