It features a radial through-hole package with a rectangular disc shape and a lead spacing of 10.2 mm. The component has a maximum current rating of 100 A, a trip current of 18.5 A, and a time to trip of 9 seconds. It operates within a temperature range of -40°C to +125°C and exhibits a resistance of 15 mOhms.
Feature Summary
- Provides overcurrent surge protection for electronic equipment
- Capable of operating in high temperature ranges
- Features a radial through-hole mounting configuration
Applications
- Overcurrent surge protection in electronic equipment
- High operating temperature circuit applications
Procurement Notes
Verify the specific part number suffix against official Bourns documentation to ensure correct voltage and current ratings. Confirm that the radial through-hole package and lead spacing match the target PCB footprint requirements. Check for AEC-Q200 compliance if automotive grade certification is required for the application.
Selection Notes
Select this component when high-temperature operation up to 125°C is necessary. Ensure the maximum current rating of 100 A and trip current of 18.5 A align with the circuit's protection thresholds. Verify that the 15 mOhms resistance value does not adversely affect signal integrity or power loss in the design.
Part Context
This device belongs to the MF-RHT Multifuse series from Bourns Electronic Solutions. The series is characterized by its ability to provide resettable protection in demanding environments. The MF-RHT1000-2 variant specifically addresses needs for robust thermal performance and reliable overcurrent interruption in industrial and consumer electronics.
Replacement Considerations
Consult official Bourns substitution guides for compatible alternatives. Verify that any substitute matches the 16V rating, 10A hold current, and radial disc form factor. Ensure the replacement maintains the -40°C to +125°C operating range and similar electrical characteristics.
