The 20 A per circuit is the headline number — each contact is sized to carry bus-level current, so this header suits a main DC rail or a power input stage, not a low-current signal harness. The 5.00 mm pitch gives enough creepage for the 250 VAC rating without forcing an oversized board footprint, and the single-row layout keeps the PCB real estate tight. Silver plating on the mating surface delivers lower contact resistance than tin, but expect fewer mating cycles than a gold-plated equivalent — this is a set-and-forget power interconnect, not a frequent-disconnect field-service point. The UL94 V-0 nylon housing and -40°C to 120°C operating range confirm it for enclosed equipment inside an appliance or industrial cabinet.","metaTitle":"TE Connectivity 1-1971846-4 Header, 4 Pos 5mm, 20A","metaDescription":"TE Connectivity 1-1971846-4 vertical header, 4 positions, 5.00mm pitch, 20A, silver-plated contacts, UL94 V-0.
