Overview
The MF-RHS400-0 is a Multifuse polymer PTC resettable fuse from Bourns Inc., designed for high-temperature circuit protection. It features a radial leaded through-hole package with a maximum voltage rating of 16 V and a hold current of 4.0 A. The device operates within a temperature range of -40°C to +125°C, offering robust overcurrent safeguarding in demanding environments.
Feature Summary
- High-temperature polymer PTC construction rated for operation up to 125°C
- Radial leaded through-hole mounting style for PCB integration
- Resettable overcurrent protection mechanism eliminating nuisance tripping
Applications
- Automotive circuitry protection
- Overcurrent surge protection for high-reliability electronic equipment
- Industrial transportation systems
- Communication infrastructure components
Procurement Notes
Verify the specific hold current and voltage ratings against the official datasheet before procurement. Confirm that the radial leaded package dimensions align with the target PCB footprint. Ensure the operating environment does not exceed the specified maximum temperature limits to maintain reliable performance.
Selection Notes
Select this component when high-temperature resilience is required alongside radial mounting constraints. Compare the 16V rating and 4.0A hold current against system requirements. Consider the physical size and lead spacing for assembly compatibility. Evaluate thermal management needs given the 125°C operational limit.
Part Context
This part belongs to the Multifuse MF-RHS series, which specializes in high-temperature applications. It utilizes polymer positive temperature coefficient technology to provide resettable protection. The series is engineered for robustness in harsh conditions where standard fuses might fail or require replacement.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching electrical parameters and mechanical dimensions.
