The BM11B-SRSS-TB(LF)(SN): This is an 11-position, single-row header from JST's SH/SR series, pitched at 1.00 mm — the tightest spacing in the family. At that pitch, the board trace routing is dense: you need a 0.5 mm trace/space capability to fan out all 11 signals on a single layer.
Surface mount with solder retention
This header is surface-mount only — no through-hole option.
Active production, available per RFQ
Sourced through independent distribution channels.
