5.00 mm Pitch, 4-Position Shrouded Header — Board-to-Wire Fit
The 1971845-4 is a single-row, 4-position header from TE Connectivity's AMP Connectors line, designed for board-to-cable/wire applications.
The 250 VAC voltage rating covers most single-phase control circuits, lighting ballasts, and small appliance power feeds. The -40°C to 120°C operating range means the header can sit in an unheated warehouse or an enclosed cabinet near a heat source without derating. Glow wire compliance adds a safety margin for fault conditions in household appliances per IEC 60335-1 — a differentiator versus standard pin headers without this rating.
