0.40mm-Pitch Header for High-Density Mezzanine Stacking

The Hirose DF37B-40DP-0.4V(51) is a 40-position, dual-row header from the DF37 series, designed for board-to-board mezzanine connections where board real estate is tight. The 0.016" (0.40mm) pitch packs 40 circuits into a compact footprint, and the 0.030" (0.75mm) height above board keeps the profile low.
