Overview
The Bourns MF-RG500-0-14 is a radial, through-hole polymer PTC resettable fuse from the Multifuse MF-RG series. It features a maximum holding current (Ih) of 5 A and a trip current (It) of 8.5 A. Rated for a maximum voltage of 16 V, it offers a minimum initial resistance of 15 mOhms and a maximum post-trip resistance of 34 mOhms. The device withstands a maximum fault current of 100 A with a trip time of 2 seconds. It operates within a temperature range of -40°C to +85°C and holds AEC-Q200 automotive qualification.
Feature Summary
- Provides overcurrent protection via self-resetting polymer positive temperature coefficient technology
- Designed for high reliability in automotive applications with AEC-Q200 certification
- Features low initial resistance to minimize power loss during normal operation
- Radial leaded construction facilitates easy insertion into printed circuit boards
Applications
- Automotive electronic circuits requiring AEC-Q200 compliance
- Consumer electronics power supply input protection
- Industrial control system bus line safeguarding
Procurement Notes
Verify the specific suffix '0-14' against the manufacturer's latest datasheet to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required axial or radial orientation and terminal plating for your assembly process. Cross-reference part numbers carefully as suffixes often denote minor physical or packaging differences rather than electrical changes.
Selection Notes
Select this component when a 5 A holding current and 16 V rating are required for space-constrained automotive designs. The radial package suits through-hole mounting where surface area is limited but lead length allows for mechanical stability. Consider the 100 A maximum fault current capability for systems with significant inrush currents or short-circuit risks.
Part Context
This part belongs to Bourns' Multifuse MF-RG series, a line of radial polymer PTC devices designed for automotive and industrial markets. The series emphasizes compact size and high current handling relative to its footprint. The MF-RG500-0-14 specifically targets applications needing robust overcurrent protection with certified automotive quality standards.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include MF-RG500-0, MF-RG500-AP, MF-RG500-2, and MF-RG500-2-14 from Bourns. Cross-brand equivalents such as Littelfuse 16R500GPR, 16R500GU, and Eaton PTR016V0500-BK are also listed as parameter-matching alternatives.
