22162040

Headers, Receptacles, Female Sockets Overview

Molex part number 22162040 is a 4-position receptacle connector from the KK254 series. It features a 0.100 inch (2.54mm) pitch and utilizes gold plating on the mating interface with a thickness of 15.0µin (0.38µm). The connector is designed for board edge, through-hole, right-angle mounting. Rated for 250VAC and 2.5A, it operates within a temperature range of -40°C to 80°C. The housing is made of white polyamide (PA/nylon) with UL94 V-0 flammability rating. Mating contacts are square-shaped female cat-ear types, while termination contacts are tin-plated brass.
