MF-RX110/72-0 is a radial leaded PTC resettable fuse designed for low-voltage circuit protection up to 60V. It features a hold current (Ihold) of 1.10A at 23°C and a trip current (Itrip) of 2.20A, with an initial resistance of 0.25 Ohms and post-trip resistance of 0.38 Ohms. The device is constructed with flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements and is RoHS compliant and halogen-free. It operates reliably across a temperature range of -40°C to +85°C with thermal derating characteristics, and is commonly used in security and fire alarm systems, loudspeakers, and power transformers where automatic circuit protection and resettability are required.
