DESCRIPTION

MF-RX300/72-2 is a PTC resettable fuse designed for overcurrent protection in low-voltage power supply applications up to 72 V. The device features a 3.0 A trip current (Itrip) with a 6.0 A hold current (Ihold) at 23°C, providing reliable automatic protection that resets after the fault condition is cleared. It exhibits an initial resistance of 0.04 O at 23°C and a post-trip resistance of 0.06 O, with a maximum time to trip of 15.0 seconds at rated current. The component is constructed with flame-retardant epoxy polymer insulation meeting UL 94 V-0 requirements, is RoHS compliant, and halogen-free. Typical applications include security and fire alarm systems, loudspeaker protection, and power transformer circuits where automatic resettable overcurrent protection is required.
