PA series, Board to Cable/Wire, Header, Male Pin, 12 Positions, 2.00 mm pitch, SMT, Shrouded - 4 Wall, Locking Ramp, Tin contacts, 3 A, 250 V, UL94 V-0, Tape & Reel","salesMarkdown":"## 2.00 mm pitch, 12 positions, locking ramp The BM12B-PASS-1-TFT: JST PA series header, 12 positions on 2.00 mm pitch, SMT with a shrouded 4-wall housing and locking ramp. ## Three mated stack heights from one header The header supports three mated stack heights — 11.1 mm, 16 mm, and 16.2 mm — depending on the PA-series receptacle chosen. That means the same board-side header can serve different enclosure depths or cable-dress requirements without a footprint change. Board guide, pick-and-place pad, and solder retention features are built in for automated assembly. The tape-and-reel packaging (Cut Tape also available) feeds directly into a pick-and-place line. RoHS compliant per JST's current declaration. ## 10-position sibling for SKU rationalization The BM10B-PASS-1-TFT is the 10-position version of the same header — same 2.00 mm pitch, same 3 A rating, same locking ramp and stack heights. If your build uses both 10- and 12-position PA receptacles, one header family covers both; no second qualification needed.","metaTitle":"BM12B-PASS-1-TFT JST PA Series Header 12 Pos 2 mm SMT","metaDescription":"JST PA series 12-position shrouded header, 2.00 mm pitch, SMT, locking ramp, 3 A, 250 V.
