B4B-XH-A
by JST
JST’s B4B-XH-A is a four-position through-hole board connector from the XH family, suited to bringing discrete wiring onto a PCB for power, signals, or internal harness connections. Its simple four-contact arrangement makes it practical wherever a compact, polarized wire-to-board interface is needed. The download includes a four-pin schematic symbol, the CONN-TH_B4B-XH-A-LF-SN footprint with four through-hole pads, and a matching 3D model for mechanical review. This conversion has been used by 3 ProtoFlow engineers in real designs, providing direct evidence of the imported component’s practical use. The part and its verified KiCad assets can also be opened directly in ProtoFlow.
