The 0.80 mm insulation height keeps the component profile low, which helps with clearance under neighbouring components on the board. ## Comparing to a 10-Position Sibling The difference is circuit count: 20 positions vs 10. The 10-position version uses tin on the post side (50 µin) instead of gold flash.","metaTitle":"10166143-00020C1LF Amphenol ICC (FCI) Minitek127 1.27mm","metaDescription":"Amphenol ICC (FCI) Minitek127 1.27mm pitch, 20-position, unshrouded SMT header.
