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. Sourced through independent distribution channels.","metaTitle":"1971845-4 TE Connectivity 4-Pin Header, 5.00mm Pitch","metaDescription":"1971845-4 TE Connectivity AMP Connectors header, 4 positions, 5.00mm pitch, through hole, shrouded, latch holder, UL94 V-0.
