MF-RG300-2

Overview

The Bourns MF-RG300-2 is a polymer PTC resettable fuse from the Multifuse MF-RG series, designed for PCB mount applications. It features a radial package with a lead spacing of 5.1 mm. Key electrical parameters include a maximum voltage of 16 VDC, a hold current of 3 A, and a trip current of 5.1 A. The device has a maximum rated current of 100 A and an initial resistance of 65 mohms. It operates within a temperature range of -40°C to +85°C.

Feature Summary

Utilizes polymer PTC technology for automatic circuit protection that resets after fault clearance.
Designed for high-current applications with a maximum rated current capacity of 100 A.
Complies with automotive qualification standards including AEC-Q200.
Features a radial through-hole package suitable for standard PCB mounting.

Applications

Automotive electronics circuits requiring AEC-Q200 compliance
Overcurrent protection in industrial control systems
Consumer electronic device power input protection

Procurement Notes

Verify the specific suffix designation against official Bourns documentation to confirm packaging type and tolerance specifications. Ensure the selected variant matches the required hold current and voltage ratings for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component based on the required 3 A hold current and 16 VDC maximum voltage rating. Consider the 65 mohms initial resistance for potential voltage drop impacts in low-voltage circuits. Verify that the operating environment stays within the specified -40°C to +85°C temperature range. Ensure the physical dimensions fit the available PCB space for the radial lead configuration.

Part Context

This component belongs to the Bourns Multifuse MF-RG series of polymer PTC resettable fuses. The series offers various hold currents and package options for circuit protection. The MF-RG line is characterized by its ability to handle high fault currents and its suitability for automotive and industrial applications requiring reliable overcurrent protection.

Replacement Considerations

Consult official Bourns documentation for direct replacements or parameter-equivalent alternatives within the MF-RG series. Verify compatibility of hold current, trip current, and maximum voltage ratings when substituting with other manufacturers' components.
