MF-R075 Description

Short technical summary and product information.

The Bourns MF-R075 is a polymeric positive temperature coefficient (PTC) resettable fuse designed for overcurrent protection in electronic circuits. It features a hold current of 750 mA at 23°C and a trip current of 1.50 A, with a maximum voltage rating of 60 V and a maximum interrupt current of 40 A. The device has an initial resistance range of 0.18 to 0.40 Ω and a maximum 1-hour resistance of 0.60 Ω, ensuring reliable performance after tripping. The time to trip at 3.75 A is 6.3 seconds maximum, and the typical tripped power dissipation is 0.90 W.

 

The MF-R075 is housed in a radial disc package with a diameter of 10.40 mm and thickness of 3.10 mm, with a seated height of 16.00 mm and lead spacing of 5.10 mm. It is designed for through-hole mounting and operates over a temperature range of -40°C to 85°C. This fuse is RoHS compliant, halogen free, and carries a California Proposition 65 warning. Typical applications include overcurrent protection in power supplies, consumer electronics, and industrial equipment.
