The 20-position variant 20021521-00020C4LF doubles the circuit count in the same 1.27mm pitch and row spacing — same gold plating, same current rating, same SMT footprint scaling to 20 circuits for higher-density board-to-cable connections.","metaTitle":"20021521-00010C4LF – Amphenol ICC Minitek127 1.27mm Header","metaDescription":"20021521-00010C4LF: Minitek127® header, 10 positions, 1.27mm pitch, SMT, gold 10µin, shrouded, UL94 V-0.
