B4B-PH-K-S
by JST
The JST B4B-PH-K-S is a four-position through-hole header used to bring a compact wire harness onto a PCB. As part of the JST PH connector family, it provides a polarized board interface for low-conductor-count signal or power wiring, while the vertical header format keeps cable entry above the board. This library entry contains a 4-pin symbol, the CONN-TH_B4B-PH-K-S footprint with four through-hole pads, and an included 3D model for assembly-space checks. The conversion’s connectivity has been exercised in real designs by 7 ProtoFlow engineers, providing practical verification beyond a catalog-only entry. The header can be opened directly in ProtoFlow and placed into the working design.
