Overview
The S4B-ZR-SM4A-TF(LF)(SN) is the 4-circuit member of JST's ZH series board-to-cable/wire header line. It carries tin-plated mating contacts rated 1 A and 50 V, mounts surface-mount right-angle with solder termination, and uses a 1.50 mm pitch.
Series & positions
Within the ZH series the S4B-ZR-SM4A-TF(LF)(SN) carries 4 positions against the 6 of the S6B-ZR-SM4A-TF — the pitch, current rating, voltage, and tin plating are shared across the series, so match the position count to circuit count.
