The Bourns MF-RX135/72-2 is a polymeric PTC resettable fuse from the MF-RX/72 series, designed for overcurrent protection in low voltage circuits up to 72V. It has a hold current of 1.35A and a trip current of 2.70A, with a maximum current rating of 40A. The initial resistance ranges from 120mΩ typical to 300mΩ maximum, and the post-trip resistance is 380mΩ maximum. The time to trip at 1.35A is 9.6 seconds maximum, with a typical tripped power dissipation of 1.70W.
This component is housed in a radial disc package with a lead spacing of 5.10mm, measuring 12.26mm in length, 3.10mm in width, and a seated height of 18.26mm. It is designed for through-hole mounting and operates over a temperature range of -40°C to 85°C. The device uses a cured, flame retardant epoxy polymer insulating material that meets UL 94 V-0 requirements.
The MF-RX135/72-2 is suitable for applications such as security and fire alarm systems, loudspeakers, and power transformers. It is RoHS compliant, lead-free, and halogen-free, with agency recognitions including cUL and TÜV.
