MF-USML700-2 is a low-ohmic PTC resettable fuse designed for thermal protection and overcurrent limiting in compact electronic devices. This surface mount component features a 1210 footprint with ultra-low resistance of 0.0010 Ohms at 23°C, a maximum voltage rating of 6V, and a maximum current rating of 50A. The device exhibits a hold current (Ihold) of 7.00A and a trip current (Itrip) of 14.00A, with a maximum time to trip of 35.00 seconds at 23°C. Operating across a temperature range of -40°C to +85°C, the MF-USML700-2 is RoHS compliant and halogen-free, making it suitable for thermal protection in Li-ion battery packs, USB port protection (USB 2.0, 3.0, and OTG), mobile phones, digital cameras, game consoles, and PC motherboards. The component is supplied in tape and reel packaging per EIA 481 standard and requires reflow soldering for assembly.
