Female housing
2–20 positions; white or transparent
Female crimp terminal
28–22AWG wire; tin or full gold-flash finish
Male PCB header
2–20 positions; vertical or right-angle; with or without kink
PCB457 identifies the family. Individual component suffix numbers and package quantities are unspecified. Specify the housings, terminals and headers needed for the intended assembly.
