The through-hole termination and push-pull fastening suit it for permanent board-to-board connections where the mating pair is not frequently disconnected. The 0.100\" (2.54mm) pitch and 0.100\" (2.54mm) row spacing define the board footprint — a 2x4 grid of 0.025\" square pins. The 0.190\" (4.83mm) mating pin length provides enough reach to engage standard female headers. The 0.120\" (3.05mm) post length suits typical 1.6mm-thick PCBs. The 100 µ\" (2.54µm) tin plating on both mating and post surfaces is adequate for moderate mating cycles (tens, not hundreds) and is cost-effective for production runs where gold is not required.","metaTitle":"Amphenol BERGSTIK II 79425-404HLF Header, 4 Pos, 2.54mm","metaDescription":"79425-404HLF BERGSTIK II unshrouded header, 4 circuits, 0.100\" pitch, 5A, 110V, tin-plated, UL94 V-0.
