For compact harnesses, this 1.25 mm pitch SMT vertical header provides a single-row interface with end hold-down tabs for reliable reflow attachment. The insulator body height is 4.30 ± 0.25 mm, with 1.60 mm (min) standoff noted for paste clearance. Terminals and solder tabs are phosphor bronze, tin over nickel, and the housing is LCP UL94V-0 (natural color). The recommended PCB layout specifies 1.25 mm pad pitch with 0.80 mm pad width and anchor pads at both ends; dimensions scale by circuit count per the on-drawing table (2–10 poles). A lock configuration is defined by circuits: 2–3 pins = lock “1”; ≥4 pins = lock “2.”
Electrical ratings are 1.0 A AC/DC and 125 V AC/DC, with contact resistance ≤20 mΩ, insulation resistance ≥100 MΩ, and withstand voltage 500 VAC for 1 minute. Operating temperature is –25 °C to +85 °C. This header is RoHS compliant.
Overall, this PCB connector delivers a robust wire-to-board solution with proven materials, consistent plating stack, and a clear dimensional table to select the correct length by pole count.
