MF-R090-0-9 is a radial-leaded PTC resettable fuse designed for overcurrent protection in low-voltage power supply applications. It features a maximum voltage rating of 60 V, a hold current (Ihold) of 0.90 A, and a trip current (Itrip) of 1.80 A, with an initial resistance of 0.31 O at 23°C. The device exhibits a 1-hour post-trip resistance of 0.47 O maximum and a maximum time to trip of 4.5 seconds at 23°C, with typical tripped power dissipation of 1.00 W. The component is constructed with flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements, is RoHS compliant and halogen-free, and features Sn/CuFe lead material. This fuse is ideal for protecting circuits in computers, peripherals, and general electronics where automatic reset capability and reliable overcurrent protection are required.
