The connector relies entirely on the through-hole solder joints for mechanical retention — in a high-vibration environment, consider a secondary board lock or a potting compound around the pins. Overall contact length is 0.450 inches (11.43 mm), with a 0.230-inch mating pin and a 0.120-inch solder tail. The 0.120-inch post length works with standard 1.6 mm PCBs — the pin protrudes enough for a clean solder fillet without bottoming out against the board. The 77313-818-18LF shares the same pitch, row spacing, plating, and current rating as the 12-position 77313-818-12LF and the 14-position 77313-818-14LF. If your BOM drops from 18 to 12 circuits, the 12-position sibling fits the same board footprint without a layout change. For a 20-position version, the 77313-818-20LF is the next step up — same series, same electrical ratings, same 0.100-inch grid. RoHS compliant and housed in UL94 V-0 thermoplastic. The bag packaging (standard tube or tape-and-reel not confirmed for this MPN) means the pins are shipped loose — plan for manual handling or a vibratory feeder if automating insertion.","metaTitle":"77313-818-18LF BERGSTIK Header 18 Pos 2.54mm Pitch","metaDescription":"Amphenol ICC (FCI) BERGSTIK 18-position unshrouded header, 0.100\" pitch, 3A per contact, gold or GXT plating.
