22027103

Headers, Receptacles, Female Sockets Overview

The Molex 22027103 is a KK 254 PC Board Connector receptacle designed for top entry and end-to-end stackable applications. It features a 2.54mm pitch with 10 circuits and utilizes through-hole termination. The connector employs brass contacts with 2.5µm tin plating on the mating interface and tin plating on the termination side. Rated for a maximum current of 4.0A per contact and a maximum voltage of 500V, it operates within a standard temperature range. The housing is made of natural nylon resin with a 94V-0 flammability rating, offering partial shrouding and polarization to ensure correct PCB orientation.
