Overview
The Bourns MF-RHT750-0-14 is a high-temperature polymer positive temperature coefficient (PPTC) resettable fuse from the Multifuse MF-RHT series. Designed for radial leaded PCB mounting, it provides overcurrent protection in demanding environments. Key electrical parameters include a hold current of 7.5 A and a trip current of 13.1 A at a maximum voltage of 16 VDC. The device features a low resistance of 22 mOhms and supports a maximum fault current of 100 A. It operates within a temperature range of -40°C to +125°C and has a power dissipation rating of 4.5 W.
Feature Summary
- High-temperature polymer PTC element designed for robust circuit protection in harsh conditions
- Radial leaded package facilitates through-hole PCB integration
- AEC-Q200 qualified for automotive-grade reliability standards
Applications
- Automotive electronic circuits requiring high-temperature resilience
- High-reliability industrial equipment overcurrent protection
- Consumer electronics with space-constrained layouts
Procurement Notes
Verify the specific suffix against official documentation to confirm exact physical dimensions and packaging configuration. Ensure the selected variant matches the required hold current and voltage ratings for the target application. Confirm RoHS compliance status via the manufacturer's datasheet before procurement.
Selection Notes
Select this component when applications demand high thermal stability and high holding currents in compact radial packages. The 16 VDC rating suits low-voltage DC systems. Verify that the 7.5 A hold current aligns with normal operating loads to prevent nuisance tripping while ensuring adequate protection against short circuits.
Part Context
This part belongs to the Bourns Multifuse MF-RHT series, which specializes in high-temperature PPTC devices. These components are engineered to eliminate tripping caused by ambient temperature variations while offering cost-effective protection against shorts. The series is widely used in automotive and industrial sectors where standard PTCs may fail under thermal stress.
Replacement Considerations
Consult official substitution guides for equivalent radial PPTC fuses with matching 7.5 A hold current and 16 VDC ratings. Verify that any replacement maintains AEC-Q200 qualification if automotive use is intended. Ensure physical footprint compatibility for radial leads.
