The 0.134\" (3.40mm) post length is long enough for a standard 1.6mm board with a good solder fillet on the bottom side. ## Rated 3A per contact at 250V, UL94 V-0 housing Each contact is rated 3A at 250V. The 3A figure is per circuit at the rated temperature — if you're running all 12 positions at current, the total heat is within the housing's thermal budget.","metaTitle":"JST S12B-XADSS-N(LF)(SN) 12-Position 2.50mm Header, Active","metaDescription":"JST XAD series 12-position dual-row header, 2.50mm pitch, shrouded with locking ramp.
