Overview
The Bourns MF-RHT1300-AP-14 is a resettable PTC fuse from the MF-RHT series, designed for high-temperature applications. It features radial leads and operates within a voltage range up to 16 VDC. The device maintains a hold current of 13 A and trips at 26 A, with a maximum trip current rating of 100 A. Its resistance is 7 mΩ, and it functions between -40°C and +125°C. The component has a lead spacing of 10.2 mm and is supplied in an ammo pack.
Feature Summary
- Provides overcurrent protection through automatic reset functionality after fault clearance.
- Engineered for reliable operation in high-temperature environments up to 125°C.
- Utilizes radial leaded construction for through-hole PCB mounting.
Applications
- Automotive electronics requiring AEC-Q200 compliance
- Industrial equipment circuit protection
- High-current power supply input stages
Procurement Notes
Verify the specific suffix AP-14 against official Bourns documentation to confirm packaging and tape-and-reel specifications. Ensure the 16VDC rating aligns with your system's maximum operating voltage. Confirm that the 13A hold current meets your circuit's continuous load requirements without nuisance tripping. Cross-reference the 7mΩ resistance value for thermal management calculations.
Selection Notes
Select this component when high current capacity and temperature resilience are critical. The radial lead style suits through-hole assembly processes. Compare the 13A hold current against peak load currents to ensure proper sizing. Consider the 10.2mm lead spacing for PCB layout constraints. Verify compatibility with reflow soldering profiles if applicable.
Part Context
This part belongs to the MF-RHT series of high-temperature PPTC resettable fuses by Bourns. These devices are commonly used in automotive and industrial sectors where standard polymeric fuses may fail due to heat. The series offers various current ratings to suit different circuit protection needs while maintaining a compact form factor.
Replacement Considerations
Check for direct substitutes within the MF-RHT series with similar hold currents. Verify that any replacement matches the 16VDC voltage rating and radial lead configuration. Ensure the alternative component also meets AEC-Q200 standards if automotive use is intended. Confirm physical dimensions fit the existing PCB footprint.
