Silver plating on both the mating tab and the solder post keeps contact resistance low for that current level. The housing is fully shrouded with four walls and a latch holder, so the mated pair locks together and won't shake loose in a vibrating panel or enclosure. Each tab is a rectangular copper alloy contact rated 20 A per circuit within the -40°C to 120°C operating range. The 250 VAC rating provides headroom for industrial control voltages. It's RoHS compliant per the manufacturer.","metaTitle":"TE Connectivity 1971846-4 Header, 4 Pos, 5mm, 20A","metaDescription":"TE Connectivity 1971846-4 vertical header, 4 positions, 5.00mm pitch, 20A, silver contacts, shrouded, latch holder.
