MF-R075-AP-17

Ptc Resettable Fuses Overview

The Bourns MF-R075-AP-17 is a resettable polymer positive temperature coefficient (PPTC) device from the Multifuse series, designed for overcurrent protection in surface mount applications. It features an axial leaded configuration with a strap-style termination, suitable for high-current circuits requiring robust fault protection. The component operates within a standard voltage range and provides trip characteristics optimized for industrial and consumer electronics. Its construction utilizes a conductive polymer composite that increases resistance significantly upon overheating, effectively limiting current flow during short circuit or overload conditions to safeguard downstream components.
