MF-USMF075-2 is a PTC resettable fuse designed for fast-acting circuit protection in surface mount applications. This device features a hold current (Ihold) of 0.75 A and a trip current (Itrip) of 1.50 A at 23°C, with a maximum voltage rating of 6 V and maximum current rating of 40 A. The fuse exhibits a resistance of 0.070 O at 23°C and provides a maximum time to trip of 0.450 seconds, with typical tripped power dissipation of 0.10 W. The compact 1210 footprint enables automated assembly and integration into space-constrained applications such as USB port protection, HDMI source protection, mobile phones, and digital cameras. The device is AEC-Q200 compliant, RoHS compliant, halogen-free, and operates reliably across the temperature range of -40°C to +85°C.
