A shrouded 4-wall housing with latch holder secures the mating receptacle against vibration, and the UL94 V-0 polyamide body meets enclosure flame-rating requirements. ## Glow Wire and Temperature Range This header is glow wire compliant. ## Plating and Contact Design Silver plating on both the mating tab and the solder post is the right call for a power interconnect: silver's bulk conductivity beats tin, and at 20 A the current density keeps the contact interface below the threshold where silver sulfide tarnish becomes a concern. The rectangular tab contact shape provides a larger mating surface area than a round pin at the same pitch, reducing contact resistance under load.","metaTitle":"TE 1971846-2 Header, 2 Pos, 5mm Pitch, 20A, Silver","metaDescription":"TE Connectivity 1971846-2 header, 2 positions, 5.00 mm pitch, 20 A, silver plating, UL94 V-0, glow wire compliant.
