The Bourns MF-R250 is a polymeric Positive Temperature Coefficient (PTC) resettable fuse designed for overcurrent protection in electronic circuits. It is part of the MF-R series and offers a hold current of 2.5 A at 23°C, with a trip current of 5 A. The device can withstand a maximum voltage of 30 V and a maximum current of 40 A.
Key electrical characteristics include an initial resistance range of 0.025 Ω to 0.048 Ω at 23°C, and a maximum post-trip resistance of 70 mΩ. The time to trip at 12.5 A is 10.3 seconds maximum, and typical tripped power dissipation is 1.2 W. The operating temperature range is -40°C to 85°C.
The MF-R250 is housed in a radial disc package with through-hole mounting. It has a lead spacing of 5.10 mm and dimensions of 12.00 mm length, 3.00 mm width, and 18.30 mm height. The device is recognized by cUL and TÜV agencies and has a flammability rating of UL 94V-0.
This PTC resettable fuse is suitable for various overcurrent protection applications where automatic reset after fault condition is desired. It is compliant with RoHS, lead-free, and halogen-free requirements.
