Product details

1.00 mm pitch, 40 positions — board-fit anchor for signal interconnect

The BM40B-SRDS-A-G-TF: This is a 40-position, dual-row shrouded header from JST's SHD series, pitched at 0.039" (1.00mm) — the defining footprint dimension for PCB layout. The 6.3 mm mated stacking height sets the z-axis clearance to the mating receptacle. With a 1 A per contact current rating and a 50 V voltage ceiling, this is a signal-only interconnect, not a power path. The header uses gold-plated male pins on phosphor bronze contacts, housed in a natural polyamide (glass-filled) UL94 V-0 body.

Frequently asked questions

Is BM40B-SRDS-A-G-TF RoHS compliant?

No, the BM40B-SRDS-A-G-TF is listed as RoHS non-compliant. For RoHS-regulated assemblies, use the BM40B-SRDS-G-TF or BM40B-SRDS-G-TF(LF)(SN) — both are functionally identical with the same pitch, positions, and ratings.

What is the pitch of BM40B-SRDS-A-G-TF?

The mating pitch is 0.039" (1.00mm), a dual-row layout with 40 positions loaded.
