What This Header Connects and Why It Works
The B12B-PNDZS-1(T)(LF)(SN): With a 12.9 mm mated stack height and a through-hole solder termination, this header suits wire-to-board harnesses where the PCB is fixed and the cable assembly is field-replaceable.
Pitch, Current, and the Board Footprint
The 250 V voltage rating is a maximum working voltage — derate it for altitude or pollution degree per the system-level safety standard. Compared to the 10-position B10B-PNDZS-1 or the 14-position B14B-PNDZS-1 (T)(LF)(SN) in the same series, this 12-position variant fills the middle of the position-count range while sharing the identical pitch, current, voltage, stack height, and locking ramp features.
