The surface-mount package includes pick-and-place features and solder retention pads for automated assembly, and the gold-plated contacts (1.97µin thickness) suit signal-level interconnect duty in compact consumer, industrial, and telecom devices. ## Mating and Assembly Notes The header mates with the Hirose DF40C series receptacle (e.g., DF40C-20DS-0.4V(58)), forming a board-to-board stack height of 0.045\" (1.14mm). The outer shroud contacts provide alignment during mating and reduce the risk of pin stubbing. No special tooling is required beyond standard SMT placement equipment; the pick-and-place feature and solder retention pads are integrated into the package.","metaTitle":"Hirose DF40TC-20DP-0.4V(58), 0.40mm Pitch, 20-Pin Header","metaDescription":"Hirose DF40TC-20DP-0.4V(58) 0.40mm pitch SMT header, 20 positions, 1.14mm stack height.
