Overview
The Bourns MF-RHS650-0 is a radial leaded polymer positive temperature coefficient (PPTC) resettable fuse designed for high-temperature circuit protection. It features a maximum voltage rating of 16V and a hold current of 6.5A, with a trip current of 12A. The device offers a maximum interrupting rating of 100A and a typical resistance of 50mΩ. It operates within a temperature range of -40°C to +125°C and utilizes a bulk packaging format.
Feature Summary
- Provides overcurrent protection through automatic resistance increase upon thermal activation
- Eliminates the need for manual replacement after fault clearance
- Designed for robust performance in high-temperature environments
Applications
- Overcurrent protection in automotive electronic circuits
- Surge protection for industrial communication systems
- Fault protection in consumer electronics power supplies
- Safety system circuit monitoring
Procurement Notes
Verify that the specific part number matches the required hold and trip currents for your application design. Confirm compliance with RoHS directives by checking the latest manufacturer datasheet. Ensure the radial lead spacing aligns with your PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a low-voltage, high-current resettable fuse is required for through-hole mounting. Consider the 16V rating and 6.5A hold current against your circuit's normal operating parameters. Evaluate the thermal environment to ensure the +125°C maximum operating temperature meets system constraints.
Part Context
This device belongs to the MF-RHS series of self-resetting fuses from Bourns. These components are engineered as PTC thermistors to replace traditional fusible links in applications requiring repeated overcurrent events. The series provides a cost-effective solution for protecting sensitive electronics from short circuits and excessive current loads.
Replacement Considerations
Consult official substitution guides for equivalent radial leaded PPTC devices with matching 16V ratings and similar current characteristics. Verify that any alternative maintains the same thermal performance and package dimensions for direct board compatibility.
