It uses a 1.27mm pitch on both the row and column spacing, which sets the board footprint for a dense, space-efficient interconnect. The gold-plated mating interface (10µinch) provides reliable contact resistance over repeated mating cycles, while the tin-plated solder tails (50µinch) are compatible with standard lead-free reflow profiles. ## SMT Termination with Pick-and-Place Ready Packaging Termination is surface-mount solder, and the part ships in Tape & Reel packaging with a Pick and Place feature — meaning the header is vacuum-pickup compatible for automated placement.","metaTitle":"20021121-00040C4LF Amphenol ICC Minitek127 1.27mm 40-Pin","metaDescription":"20021121-00040C4LF Amphenol ICC Minitek127 1.27mm pitch, 40-position dual-row SMT header.
