The BSMD1206L-450 is a resettable fuse manufactured by BHFuse. It has 6V of voltage, 4.5A of current, 50A of peak current, 1.5W of power dissipation, an operating temperature range of -40°C to +85°C, 9A of tripping current, 1mO of resistance, 5s of time-lag, and 15mO of hold current in a 1206 SMT package. It is compliant with ROHS standards. It is designed to detect fault resistance levels and shutdown respective circuit limits to protect from over-current/over-heating/short-circuits.
