MF-R110-2 is a radial-leaded PTC resettable fuse designed for automatic circuit protection in low-voltage power supply applications. It features a maximum voltage rating of 30 V and a maximum current rating of 40 A, with a hold current (Ihold) of 1.10 A and a trip current (Itrip) of 2.20 A at 23°C. The device exhibits an initial resistance of 0.18 O and a post-trip resistance of 0.27 O (maximum at 23°C), with a maximum time to trip of 6.6 seconds and typical tripped power dissipation of 0.70 W. Constructed with cured, flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements, the device is RoHS compliant and halogen-free. It is commonly used in computers, peripherals, and general electronics where automatic load protection is required.
