Overview
Bourns Inc. MF-RG500-2 is a Multifuse® polymer PTC resettable fuse rated for 16V maximum voltage and 5A hold current. It features radial through-hole mounting with disc-style termination and an initial resistance of 15 mOhms minimum. The device trips at 8.5A within 2 seconds and withstands a maximum fault current of 100A. Operating temperature range is -40°C to 85°C, and it holds AEC-Q200 automotive qualification.
Feature Summary
- Polymer positive temperature coefficient technology provides automatic self-resetting functionality after fault clearance without manual replacement.
- Radial leaded construction facilitates standard through-hole PCB integration for robust mechanical attachment.
- Automotive-grade certification ensures reliability under demanding thermal and electrical conditions specified by industry standards.
Applications
- Automotive electronic circuit protection
- Power supply overcurrent safeguarding
- Consumer electronics input protection
Procurement Notes
Verify the specific suffix '2' against official Bourns documentation to confirm exact packaging or tape-and-reel specifications. Ensure the selected variant matches the required hold current and voltage ratings for the target application circuit design parameters.
Selection Notes
Select this component when a 5A continuous current capacity and 16V system voltage are required. Consider the 8.5A trip threshold and 100A maximum fault current capability for short-circuit scenarios. Verify that the radial package dimensions fit the available PCB footprint and mounting constraints.
Part Context
The MF-RG series represents Bourns' line of high-current resettable fuses designed for automotive and industrial applications. This model belongs to the Multifuse family, utilizing proprietary polymer composite materials to deliver fast response times and durable cycling performance in overcurrent protection roles.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include MF-RG500-AP-14, MF-RG500-0, MF-RG500-AP, and Littelfuse 16R500GPR. Verify electrical compatibility before substitution.
