JST PH Connector Header Through Hole 3 position 0.079" (2.00mm)
The B3B-PH-K-S(LF)(SN) is a 3-position, 2.0 mm pitch, through-hole (THT) male header from the JST PH series, designed for wire-to-board connections.
It is a top-entry, shrouded connector that mates with JST PH crimp housings, commonly used for compact internal wiring in electronic devices such as consumer electronics, battery connections, and embedded systems.
This connector is optimized for high-density PCB layouts, offering a reliable and secure connection with a locking mechanism and low contact resistance.
