SHD series, Board to Cable/Wire header, 40 positions, 1.00mm pitch, SMT, shrouded 4-wall, gold-plated male pins, 1A per contact at 50V, -25°C to 85°C operating range.","salesMarkdown":"## 40-position 1mm pitch SMT header for board-to-wire assemblies Surface-mount termination with solder retention and pick-and-place features streamlines automated assembly. Each contact is rated 1A at 50V, suitable for signal-level currents and low-power distribution within an enclosure. The UL94 V-0 glass-filled nylon housing provides flame retardancy for equipment inside an enclosure. Phosphor bronze contacts with gold finish maintain low contact resistance over the rated temperature span. Packaging options include Tape & Reel and Cut Tape for volume or prototype builds. The base product number BM40B-SR covers variants with different plating or additional features like board guide. ## Mates with JST SHD series receptacles This header mates with JST SHD series female receptacles (crimp or IDC type) to form a board-to-wire connection. The push-pull fastening type and 6.3mm mated stacking height define the mechanical envelope. The 1.00mm pitch and 40-position count must match the receptacle; confirm the mating half part number before committing the BOM line. Gold-to-gold contact interface ensures reliable signal transfer over multiple mate cycles.","metaTitle":"BM40B-SRDS-G-TF JST SHD 40-Pos 1mm Pitch SMT Header","metaDescription":"JST SHD series header, 40 positions, 1.00mm pitch, SMT, gold contacts, 1A/50V, -25°C to 85°C.
