The 6.3 mm mated stacking height sets the z-axis clearance to the mating receptacle. With a 1 A per contact current rating and a 50 V voltage ceiling, this is a signal-only interconnect, not a power path. The header uses gold-plated male pins on phosphor bronze contacts, housed in a natural polyamide (glass-filled) UL94 V-0 body.","metaTitle":"BM40B-SRDS-A-G-TF JST SHD 40-Pos 1mm Header – SMT","metaDescription":"JST BM40B-SRDS-A-G-TF SHD series header, 40 positions, 1.00 mm pitch, SMT, shrouded, gold-plated pins.
