Overview
The Bourns MF-RHT1300-2 is a high-temperature PTC resettable fuse from the MF-RHT series, designed for through-hole radial mounting. It features a hold current of 13 A and a trip current of 26 A at a maximum voltage of 16 VDC. The device has a maximum fault current rating of 100 A and a typical resistance of 7 mΩ. It operates within a temperature range of -40°C to +125°C with a lead spacing of 5.1 mm.
Feature Summary
- Provides overcurrent protection through automatic reset functionality upon cooling after tripping.
- Engineered for high-temperature environments with stable performance up to 125°C.
- Utilizes radial leaded construction for reliable through-hole PCB integration.
Applications
- Automotive electronics circuits requiring AEC-Q200 compliance
- Industrial power supply protection systems
- Consumer appliance overcurrent safeguarding
Procurement Notes
Verify that the specific ordering suffix matches the required package format, as variations exist between bulk and tape-and-reel configurations. Confirm that the 16VDC rating aligns with the circuit's maximum operating voltage. Ensure the radial lead spacing of 5.1 mm fits the target PCB footprint. Cross-reference the datasheet for precise thermal derating curves relevant to the installation environment.
Selection Notes
Select this component when a 13A hold current and 16VDC rating are required for high-temperature applications. The MF-RHT series offers AEC-Q200 qualification, making it suitable for automotive use. Compare against the MF-RHS series if higher voltage ratings or different physical dimensions are needed. Ensure the 7mΩ resistance meets the circuit's voltage drop constraints.
Part Context
This part belongs to the Bourns MF-RHT series of high-temperature PPTC resettable fuses. The series is characterized by its ability to withstand elevated temperatures while maintaining electrical stability. It serves as a protective component in circuits where standard polymeric devices might fail due to thermal stress, offering a robust solution for demanding industrial and automotive environments.
Replacement Considerations
The MF-RHS1300-0 is a similar radial leaded PTC with identical electrical ratings but may differ in physical height and packaging. Verify mechanical fit and thermal characteristics before substitution. Other MF-RHT variants offer different current ratings; ensure the replacement matches the specific hold and trip current requirements of the design.
