Overview
The MF-RHT1000-2-14 is a polymeric positive temperature coefficient (PTC) resettable fuse manufactured by Bourns Inc. Designed for high-temperature environments, this component features a holding current of 10 A and a maximum voltage rating of 16 V. It utilizes a radial leaded disc package suitable for through-hole mounting applications. The device provides overcurrent protection by increasing resistance significantly upon thermal activation, effectively interrupting excessive current flow until the fault condition is removed and the unit cools down.
Feature Summary
- Polymeric PTC technology for automatic circuit recovery
- High-temperature rated construction for demanding environments
- Radial leaded disc form factor for through-hole integration
Applications
- Overcurrent protection in automotive electronics
- Industrial control circuit safeguarding
- Consumer appliance power input protection
Procurement Notes
Verify the specific suffix codes against official Bourns documentation to ensure correct voltage and current ratings. Confirm that the radial leaded configuration matches the target PCB layout requirements. Cross-reference the manufacturing date code with supply chain records to ensure component freshness and reliability standards are met before final procurement approval.
Selection Notes
Select this component when circuit protection requires resilience in elevated temperature conditions. Ensure the operating environment does not exceed the specified thermal limits defined in the datasheet. Validate that the 16 V maximum voltage rating aligns with the system's electrical parameters to prevent insulation breakdown or safety hazards during fault events.
Part Context
This part belongs to the MF-RHT series of high-temperature PTC resettable fuses from Bourns. The series is engineered to provide reliable overcurrent protection in applications where standard components might fail due to heat stress. The MF-RHT1000-2-14 variant specifically addresses needs for higher current handling within a compact radial footprint.
Replacement Considerations
Direct substitutes include other MF-RHT series variants such as MF-RHT1000-AP or MF-RHT1000-0-14, provided they match the required 10 A holding current and 16 V rating. Verify package compatibility and thermal characteristics before swapping components to maintain circuit integrity.
