The mating pin length of 0.230\" (5.84 mm) provides enough reach for standard receptacles, while the post length of 0.095\" (2.41 mm) suits boards up to about 1.6 mm thick before the solder tail protrudes beyond the bottom side. ## Current and Contact Life The tin-plated solder tails (78.7 µinch) are standard for wave solder wetting. Bulk packaging is the standard package option.","metaTitle":"77311-101-20LF BERGSTIK Header 20 Pos 2.54mm Pitch","metaDescription":"Amphenol ICC (FCI) BERGSTIK unshrouded header, 20 positions, 0.100\" pitch, 3 A per contact, gold mating finish, UL94 V-0.
