If your board stack-up needs the longer 0.525\" pin for a deeper receptacle, the 77311-103-02LF is the one. The 1-position 77311-101-01LF is a single-pin variant for applications needing only one circuit.","metaTitle":"77311-103-02LF Amphenol ICC (FCI) BERGSTIK® Header 2-Pin","metaDescription":"Active 2-position unshrouded header, 0.100\" pitch, 3A per contact, gold-plated mating surface.
