The Bourns MF-RX375/72-0 is a polymeric PTC resettable fuse from the MF-RX/72 series. It is designed for overcurrent protection in low voltage circuits up to 72V. With a hold current of 3.75A and a trip current of 7.50A, it provides reliable protection.
Electrical characteristics include a maximum current rating of 40A, initial resistance range of 30 mΩ to 80 mΩ (typical 50 mΩ), and post-trip resistance maximum of 130 mΩ. The maximum time to trip at 18.75A is 24 seconds, with typical tripped power dissipation of 3.20W.
The device is housed in a radial disc package with through-hole mounting. Dimensions are 23.51mm length, 3.10mm width, 29.50mm height, and lead spacing of 10.20mm. It operates over a temperature range of -40°C to 85°C.
The MF-RX375/72-0 is RoHS compliant, lead-free, and halogen-free. It is suitable for applications such as security systems, loudspeakers, and power transformers. The epoxy polymer insulating material meets UL 94 V-0 flammability requirements.
