MF-R075-AP-99

Ptc Resettable Fuses Overview

The MF-R075-AP-99 is a resettable fuse from the MF-R series, manufactured by Bourns Inc. It utilizes Polymeric Positive Temperature Coefficient (PPTC) technology to provide overcurrent protection in electronic circuits. The component features an axial leaded package design suitable for through-hole mounting applications. Key electrical specifications include a holding current of 0.75A and a trip current of 1.50A, ensuring reliable circuit interruption under fault conditions. The device is rated for a maximum voltage of 60VDC and operates within a temperature range of -40°C to +85°C. Its low resistance characteristic minimizes power loss during normal operation.
