The contacts are male square pins with a thick 100.0µin (2.54µm) tin plating on the mating surface and tin on the solder tail — a cost-effective finish for moderate mating-cycle applications. This is a board-to-board interconnect. The through-hole solder termination anchors it into the PCB. Rated 5A per contact at the 110V voltage rating, with a UL94 V-0 housing for equipment inside an enclosure requiring flame rating. ## What the Ratings Mean The 0.100\" (2.54mm) pitch matches legacy 0.100\" socket strips. The 100.0µin (2.54µm) tin plating on the mating contacts is thick enough for repeated insertion and extraction in a bench or production setting.","metaTitle":"79425-418HLF BERGSTIK® II Header, 18 Pos, 0.100\" Pitch","metaDescription":"79425-418HLF BERGSTIK® II unshrouded header, 18 positions, 0.100\" pitch, 5A, UL94 V-0.
