Industrial temperature range fits factory-floor and outdoor gear
Rated for -40°C to 85°C ambient operation, this supervisor is suited for industrial control panels, outdoor telecom cabinets, and factory automation where the environment sees wide thermal swings but stays short of under-hood automotive extremes. The SOT-23-5 footprint keeps board area small, and the surface-mount package suits standard reflow assembly.
