MF-R250-AP-10

Overview

The Bourns MF-R250-AP-10 is a radial leaded PTC resettable fuse from the Multifuse MF-R series. It features a 2.5 A hold current and a 5 A trip current, rated for a maximum voltage of 30 V. The device exhibits a minimum resistance of 48 mOhms and supports a maximum fault current of 40 A. It operates within a temperature range of -40°C to +85°C and dissipates up to 1.2 W. Physical dimensions include a length of 12 mm, width of 3 mm, height of 18.3 mm, and a lead spacing of 5.1 mm.

Feature Summary

Provides automatic circuit protection through positive temperature coefficient polymer technology that increases resistance during overcurrent events.
Encased in cured flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements for safety compliance.

Applications

Computer and peripheral equipment power supply protection
General electronics circuit safeguarding
Automotive electronic system protection

Procurement Notes
