MF-R090-2 Description

Short technical summary and product information.

The Bourns MF-R090-2 is a polymeric PTC resettable fuse from the MF-R series, designed for overcurrent protection in a variety of electronic circuits. With a hold current of 900mA and a trip current of 1.80A, it provides reliable protection while automatically resetting after the fault is cleared.

 

Key electrical specifications include a maximum voltage of 60V and a maximum interrupt current of 40A. The initial resistance ranges from 140mΩ to 310mΩ at 23°C, with a maximum post-trip resistance of 470mΩ. The time to trip is 7.2 seconds maximum at 4.5A, and typical tripped power dissipation is 1.00W.

 

This component operates over a temperature range of -40°C to 85°C and is housed in a radial disc package with lead spacing of 5.10mm. It is RoHS compliant, lead-free, and halogen free, with cUL and TÜV agency approvals.
