B7B-EH-A(LF)(SN) – JST

Overview

The JST B7B-EH-A(LF)(SN) is a 7-position, 2.5mm pitch wire-to-board crimp-style connector header, meticulously engineered for high-density internal wiring applications. Its primary function is to facilitate robust and reliable connections between flexible flat cables (FFCs) or discrete wires and printed circuit boards (PCBs). A critical design consideration for such compact connectors is the trade-off between contact density and insulation resistance; while the EH series achieves excellent space savings, designers must ensure adequate creepage and clearance distances are maintained on the PCB to prevent unintended electrical discharge, especially in environments with fluctuating humidity or potential contamination.
