MF-RG500-AP

Overview

The Bourns MF-RG500-AP is a polymer PTC resettable fuse from the Multifuse MF-RG series, rated for 16V maximum voltage and 5A hold current. It features a trip current of 8.5A and a maximum fault current rating of 100A. The device exhibits an initial resistance of 15mΩ minimum and a post-trip resistance of 34mΩ maximum. Designed for through-hole radial mounting with a lead spacing of 5.1mm, it operates within a temperature range of -40°C to +85°C. The component measures 10.40mm in length, 3.00mm in width, and up to 14.30mm in height.

Feature Summary

Provides automatic circuit protection by increasing resistance significantly upon overcurrent conditions to interrupt flow.
Automatically resets to low-resistance state once the fault condition is removed and the device cools down.
Complies with AEC-Q200 qualification standards for automotive electronic applications.

Applications

Protection of automotive electronic circuits and wiring harnesses
Overcurrent safeguarding in consumer electronics power supplies
Interface circuit protection in industrial control systems

Procurement Notes

Verify the specific suffix AP against the official Bourns datasheet to confirm packaging configuration and material compliance. Ensure the selected variant matches the required hold current and voltage ratings for the target application circuit. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a high-current resettable fuse is required for 16V systems. The 5A hold current and 8.5A trip threshold define the operating window. Verify that the physical dimensions fit the PCB layout and that the radial lead spacing aligns with the board holes. Confirm thermal management requirements are met within the specified operating temperature range.

Part Context

This part belongs to the Bourns Multifuse MF-RG series of polymer PTC resettable fuses. These devices are designed for surface mount or through-hole applications requiring robust overcurrent protection. The series offers various current ratings and package options to suit different circuit density and current handling needs.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include MF-RG500-0 and MF-RG500-2. Verify electrical characteristics and mechanical dimensions match before substitution.
