WTB20SAD7JTA

Headers, Receptacles, Female Sockets Overview

The WTB20SAD7JTA is a rectangular MIL-DTL-55302 series board mount receptacle manufactured by Molex / AirBorn. It features 20 positions arranged in a dual-row configuration with a 2.54 mm (0.100 inch) pitch. The component utilizes through-hole termination and socket contacts made of copper alloy with gold plating. Constructed with a polyphenylene sulfide (PPS) plastic body, it operates within a temperature range of -65°C to +125°C. Rated for 5 A current and 1 kV voltage, it includes a turning jackset mechanism and mounting ears for secure installation.
