For bundles of multiple circuits, derate the per-contact current to stay within the temperature rise limits of the housing material.","metaTitle":"JST BM03B-ACHFKS-GACN-ETF(LF)(SN) Header – 1.2mm Pitch","metaDescription":"JST ACHF series 3-position header, 1.20mm pitch, SMT right-angle, gold-plated contacts.
