MF-R030 Description

Short technical summary and product information.

The Bourns MF-R030 is a polymeric PTC resettable fuse from the MF-R series. It is designed for overcurrent protection in electronic circuits, automatically resetting after the fault is cleared. Key electrical specifications include a hold current of 300 mA at 23°C, a trip current of 600 mA, and a maximum voltage rating of 60 V. The device can handle up to 40 A fault current.

 

The initial resistance ranges from 0.76 Ω to 1.36 Ω at 23°C, with a maximum post-trip resistance of 2.1 Ω. The time to trip is 3 seconds maximum at 1.5 A. Typical tripped power dissipation is 0.5 W. The operating temperature range is -40°C to 85°C.

 

The MF-R030 is packaged in a radial disc form factor with through-hole mounting. It has a diameter of 7.40 mm and thickness of 3.10 mm, with a height of 13.40 mm including leads. Lead spacing is 5.10 mm. The device is RoHS compliant, lead-free, and halogen-free per Bourns definition. It carries cUL and TÜV agency approvals.
