Product details

Board-Stacking Profile: 0.40 mm Pitch, 0.8 mm Mated Height

Two rows of contacts split the 8 positions into 4 signal and 4 power circuits, a configuration that suits compact mezzanine cards where a separate power header would waste board real estate.

The 0.030" (0.75 mm) height above board and 0.8 mm mated stacking height lock the z-axis budget.
