MF-SM185/33-2 is a surface-mount PTC (Positive Temperature Coefficient) resettable fuse designed for automotive and general circuit protection applications. It features a hold current of 1.8 A at 23°C, a trip current of 3.6 A, and a maximum voltage rating of 33 V, with a resistance of 0.04 O at 23°C. The device operates reliably across a temperature range of -40°C to +85°C and has a maximum time to trip of 8.0 seconds at rated current. With AEC-Q200 compliance and RoHS certification, this component is ideal for protecting sensitive electronic circuits in automotive systems, industrial equipment, and consumer electronics where automatic reset capability and compact form factor are required.
