The 0.016\" (0.40mm) pitch forces a tight pad layout — expect 0.20mm to 0.25mm pad width on the footprint, with trace escape routing between pads requiring a controlled impedance stack if signals run above a few hundred MHz. It is ROHS3 Compliant, which covers the EU RoHS directive's current substance restrictions.","metaTitle":"Hirose DF37B-10DP-0.4V(53) Header, 10 Pos, 0.40mm Pitch","metaDescription":"Hirose DF37B-10DP-0.4V(53) header, 10 positions, 0.40mm pitch, 0.75mm height, gold contacts, ROHS3 compliant.
