MF-RX110/72-2 Description

Short technical summary and product information.

The Bourns MF-RX110/72-2 is a polymeric PTC resettable fuse designed for overcurrent protection in low voltage circuits up to 72V. It features a hold current of 1.1A and a trip current of 2.2A, with a maximum fault current rating of 40A. The initial resistance ranges from 0.15Ω to 0.25Ω, and the post-trip resistance is 0.38Ω maximum. The maximum time to trip at 5.5A is 8.2 seconds, with typical tripped power dissipation of 1.5W.

 

This component is housed in a radial, disc package with through-hole mounting. Lead spacing is 5.1mm, and the overall dimensions are 10.84mm length, 3.10mm width, and 16.84mm height. It operates over a temperature range of -40°C to 85°C.

 

The MF-RX110/72-2 is RoHS compliant, lead free, and halogen free, with a California Prop 65 warning. It is suitable for use in security and fire alarm systems, loudspeakers, and power transformers.
