The overall contact length is 0.538\" (13.67mm), with a mating length of 0.318\" (8.08mm) and a post length of 0.120\" (3.05mm). That post length is for through-hole soldering; the board hole pattern and solder tail length are fixed by the part, so verify the board thickness and solder wave clearance against the 0.120\" post. This header mates with any standard 0.100\" pitch, 4-position female receptacle housing that accepts 0.025\" square pins — the BergStik® II system's mating interface is the square pin geometry. For vibration-prone applications, a receptacle with a positive lock or a secondary retention feature should be considered. Termination is through-hole solder to the PCB.","metaTitle":"FCI 78511-404HLF BergStik II Header, 4 Pos, 2.54mm, 5A","metaDescription":"BergStik II unshrouded header, 4 positions, 0.100\" pitch, tin-plated contacts rated 5A.
