The through-hole posts are 0.134\" (3.40mm) long, suited for standard 1.6mm-thick PCBs with enough tail length for a reliable solder fillet on the opposite side. ## Tin Contacts and the Current Ceiling The mating finish is tin, not gold — this keeps the per-unit cost down but limits the connector to roughly 30–50 mating cycles before the tin oxide layer builds resistance. For applications requiring frequent disconnect-reconnect (field-service or battery swapping), the gold-plated sibling B8B-XH-AM(LF)(SN) is the better choice. The (LF)(SN) suffix confirms RoHS compliance and a tin-plated contact finish.","metaTitle":"B8B-XH-A(LF)(SN) JST XH Header 8 Pos 2.5mm Pitch Tin","metaDescription":"JST XH series 8-position shrouded header, 2.50mm pitch, 3 A, 250 V, tin contacts.
