MF-RX030/72-AP

Overview

The Bourns MF-RX030/72-AP is a radial leaded PPTC resettable fuse from the Multifuse MF-RX/72 series. It features a 300 mA hold current and a 600 mA trip current, rated for a maximum voltage of 72 VDC. The device has a typical resistance of 1.95 Ohms and a maximum interrupt rating of 40 A. It operates within a temperature range of -40°C to +85°C. The component utilizes a bulk packaging format with a 5.1 mm lead spacing.

Feature Summary

Provides overcurrent protection through automatic polymer positive temperature coefficient (PPTC) switching behavior
Designed for high-voltage applications up to 72 VDC with robust fault tolerance
Radial leaded construction facilitates standard PCB mounting configurations

Applications

Overcurrent protection in automotive electronic circuits
Surge protection for consumer electronics devices
Industrial equipment circuit safeguarding
