The Bourns MF-R300-2 is a polymeric positive temperature coefficient (PTC) resettable fuse designed for overcurrent protection in electronic circuits. It has a hold current of 3 A at 23°C and a trip current of 6 A, with a maximum voltage rating of 30 V and a maximum interrupt current of 40 A.
This device features a low initial resistance range of 0.020 Ω to 0.050 Ω and a maximum post-trip resistance of 80 mΩ. The time to trip at 15 A is 10.8 seconds maximum, and typical tripped power dissipation is 2 W. It operates over a temperature range of -40°C to 85°C.
The MF-R300-2 is packaged in a radial disc form factor with through-hole mounting and 5.10 mm lead spacing. It measures 12.00 mm long, 3.00 mm wide, and 18.30 mm high. The component is RoHS3 compliant, halogen free, and carries cUL and TUV agency approvals.
