MF-R090 Description

Short technical summary and product information.

The Bourns MF-R090 is a polymeric PTC resettable fuse from the MF-R series, designed for overcurrent protection in a wide range of applications. It features a hold current of 900 mA and a trip current of 1.80 A, with a maximum operating voltage of 60 V and a maximum fault current of 40 A. The initial resistance ranges from 0.14 Ω to 0.31 Ω, with a maximum post-trip resistance of 0.47 Ω. At 4.5 A, the time to trip is a maximum of 7.2 seconds, and typical tripped power dissipation is 1.00 W. The device operates over a temperature range of -40°C to 85°C. The MF-R090 is housed in a radial, disc through-hole package with a lead spacing of 5.10 mm and dimensions of 11.70 mm x 3.10 mm x 16.70 mm. It is compliant with RoHS, lead-free, and halogen-free requirements, and carries a California Prop 65 warning.
