MF-R050-0-99 Description

Short technical summary and product information.

The Bourns MF-R050-0-99 is a polymeric positive temperature coefficient (PTC) resettable fuse from the MF-R series. It is designed to provide overcurrent protection in a wide range of electronic circuits. The device has a hold current of 500 mA and a trip current of 1.0 A, with a maximum voltage rating of 60V and a maximum interrupt current of 40 A.

 

This PTC fuse features a low initial resistance range of 0.41 Ω to 0.77 Ω at 23°C, and a post-trip resistance of 1.17 Ω maximum. The typical time to trip at 2.5 A is 4 seconds, and the tripped power dissipation is 0.75 W. It operates over a temperature range of -40°C to 85°C.

 

The MF-R050-0-99 is housed in a radial, disc package with a lead spacing of 5.10 mm, suitable for through-hole mounting. It is RoHS compliant and lead-free, making it suitable for environmentally conscious designs.
