The right-angle solder tails are surface-mount only; there is no through-hole variant in this order code. Confirm the board pad layout matches the 1.25mm pitch and the 8.95mm insulation height to ensure clearance to nearby components. ## Application and environment The 18-position count suits moderate I/O density on a control board or LED driver where you need a compact but serviceable interconnect. The dual-row layout keeps the connector width narrower than a single-row 18-position part at the same pitch.","metaTitle":"Molex 5054481871 Micro-Lock PLUS Header, 18 Pos, 1.25mm, SMT","metaDescription":"Molex 5054481871 Micro-Lock PLUS 18-position SMT header, 1.25mm pitch, right-angle, latch holder.
