MF-SM200-2 is a PTC resettable fuse from Bourns' MF-SM series designed for surface mount circuit protection applications. It features a hold current of 2.0 A at 23°C, a trip current of 4.0 A, and a maximum voltage rating of 15 V, with a resistance of 0.045 O at 23°C. The device operates reliably across a temperature range of -40°C to +85°C, with a maximum device surface temperature of 125°C in the tripped state, and exhibits a maximum time to trip of 8.0 seconds. This component is AEC-Q200 compliant, RoHS compliant, and halogen-free, making it suitable for automotive and industrial applications requiring automatic overcurrent protection with the ability to reset after fault conditions are cleared.
