MF-USMF075-2 Description

Short technical summary and product information.

The Bourns MF-USMF075-2 is a polymeric PTC resettable fuse from the MF-USMF series. It is designed for overcurrent protection in low-voltage applications, with a hold current of 750 mA and a trip current of 1.5 A. The device operates at a maximum voltage of 6 V and can handle a maximum current of 40 A. It features a fast time to trip of 0.1 seconds at 8 A, with a typical tripped power dissipation of 0.6 W. The resistance ranges from 0.07 Ω minimum to 0.45 Ω maximum at 23°C. This fuse is surface mountable in a 1210 (3225 Metric) concave package, measuring 3.22 mm x 2.58 mm with a maximum thickness of 0.85 mm. It is qualified to AEC-Q200 for automotive applications, and is RoHS compliant, halogen free, and REACH unaffected. The device is suitable for use in a wide operating temperature range of -40°C to 85°C.
