9-position, 3-row header with 4.14mm pitch
The 1-770182-0: This is a 9-position, 3-row vertical header from the Mini-Universal MATE-N-LOK series, on a 4.14mm pitch. Rated for 600VAC and the current rating varies by wire gauge, so the limiting factor is the wire and terminal, not the header itself. The tin-on-tin contact finish (150µin on both mating and post sides) is suited for moderate mating cycle counts in cost-sensitive designs.
Board lock and through-hole mounting
Board lock features on the through-hole mounting hold the header in place during wave soldering, preventing float and ensuring the post alignment with the PCB holes. The contact length - post is 0.175" (4.45mm), which fits standard 1.6mm PCBs with room for solder fillet.
