The Bourns MF-R185-2 is a polymeric PTC resettable fuse from the MF-R series. It is designed to provide overcurrent protection in a compact radial, disc package through-hole mounting. The device has a hold current of 1.85 A and a trip current of 3.70 A, making it suitable for applications where moderate current levels need to be protected.
The maximum voltage is 30 V and the maximum fault current is 40 A. The initial resistance at 23 °C ranges from a minimum of 0.04 Ω to a maximum of 0.07 Ω, with a maximum post-trip resistance of 0.11 Ω. The typical tripped power dissipation is 1.0 W. The time to trip at 9.25 A is 8.7 seconds maximum.
The operating temperature range is -40°C to 85°C. The component is RoHS compliant, lead free, and halogen free. It is housed in a radial disc package with a lead spacing of 5.10 mm and a size of 12.00 mm diameter by 3.00 mm thickness.
