MF-R900-2-99 is a radial-leaded PTC resettable fuse designed for overcurrent protection in low-voltage power supplies and general electronics applications. It features a maximum voltage rating of 30 V and a maximum current rating of 40 A, with a hold current (Ihold) of 9.0 A and a trip current (Itrip) of 0.005 A at 23°C. The device exhibits an initial resistance of 0.01 O and a post-trip resistance of 0.02 O maximum at 23°C, with a maximum time to trip of 20.0 seconds. The component is constructed with cured, flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements and is RoHS compliant and halogen-free. This fuse is ideal for protecting circuits in computers, peripherals, and general electronic equipment where automatic reset capability and reliable overcurrent protection are required.
