The through-hole solder tails extend 0.122\" (3.10mm) below the insulator, suitable for standard PCB thickness. ## Shrouded 4-wall with latch holder — vibration-proof mate A board guide on the insulator helps align the connector pair during blind mating, reducing pin damage in assembly. The mated stack height is 11 mm — confirm this matches the clearance between your board and the mating receptacle.","metaTitle":"JST B40B-PUDSS-1 Header – 40 Pos, 2.00mm, Shrouded, Active","metaDescription":"JST PUD series shrouded header, 40 positions, 2.00mm pitch, through-hole, latch holder, 3A/250V.
