In a production environment where a board is mated and unmated during test or rework, that gold layer buys you consistent signal integrity over hundreds of cycles. The 0.118\" (3.00mm) post length gives enough standoff for through-hole soldering on a typical 1.6mm board without bottom-side interference. ## Current, Temperature, and Flame Rating Rated 3A per contact — that is the per-pin limit at 25°C ambient; the actual system current depends on how many pins are loaded and the board's thermal environment. This is a standard compliance gate for UL-listed assemblies. The base product number is 77313; the full suffix 183-72LF encodes the plating, pin length, and packaging. No pin-compatible direct replacement from Amphenol ICC (FCI) is published, but the BERGSTIK series includes many 0.100\" pitch headers — verify the mating half and board footprint before substituting.","metaTitle":"77313-183-72LF BERGSTIK® 72-Pin Unshrouded Header","metaDescription":"Amphenol ICC (FCI) 77313-183-72LF — 72-position, 2-row, 0.100\" pitch unshrouded breakaway header.
