Overview
The Bourns MF-RG500-AP-14 is a radial leaded polymer PTC resettable fuse from the Multifuse MF-RG series, designed for through-hole PCB mounting. It features a 5 A hold current and an 8.5 A trip current, with a maximum voltage rating of 16 VDC. The device exhibits a low initial resistance of 15 mOhms (minimum) and a maximum post-trip resistance of 34 mOhms. It supports a maximum fault current of 100 A and operates within a temperature range of -40°C to +85°C. Certified to AEC-Q200 standards, it is suitable for automotive applications.
Feature Summary
- Automotive-grade reliability certified under AEC-Q200 standards
- Low resistance design minimizes power loss in normal operation
- Radial leaded package facilitates easy through-hole PCB integration
Applications
- Automotive electronic circuit protection
- Power supply input/output overcurrent protection
- Portable device battery protection
Procurement Notes
Verify the specific suffix AP-14 corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 16V rating aligns with your system's maximum operating voltage. Ensure the 5A hold current meets the continuous load requirements without nuisance tripping. Check for RoHS compliance documentation if environmental regulations apply to your region.
Selection Notes
Select this component when automotive qualification is mandatory and low voltage operation is required. The 5A hold current suits moderate power circuits. Compare the 16V rating against peak transient voltages to ensure adequate margin. Consider the radial footprint dimensions for PCB layout constraints. Evaluate the 100A max current capability against potential short-circuit scenarios.
Part Context
This part belongs to the Bourns Multifuse MF-RG series, which specializes in high-current, low-voltage resettable fuses. The series is engineered specifically for the stringent demands of the automotive industry, offering robust protection against overcurrent conditions while maintaining low profile and reliable performance in harsh environments.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include MF-RG500-0, MF-RG500-2, and Littelfuse 16R500GPR. Verify that any substitute matches the 16V rating, 5A hold current, and radial package dimensions before implementation.
