Board Layout and Pitch Fit
The 0022284224: 22 circuits on a single row means the header occupies 2.160" (54.86 mm) of board edge, leaving room for adjacent connectors or components in a dense I/O bank.
Mating Interface and Contact Plating
Gold plating on the mating face at 15.0 µinch (0.38 µm) over nickel — this is the standard thickness for moderate-cycle applications (100–500 mates) in controlled environments. The tin-plated solder tails (100.0 µinch) handle the wave-solder joint without wicking issues.
