WTB120PR9J

Overview

The WTB120PR9J is a rectangular MIL-spec connector plug from the AirBorn W Series, manufactured by Molex. It features 120 positions arranged in two rows with a 2.54 mm pitch. Designed for board mount installation, it utilizes through-hole termination and male pin contacts plated with gold. The housing is constructed from Polyphenylene Sulfide (PPS) and includes a right-angle orientation. Electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV, with an insulation resistance of 5 GOhms. It operates within a temperature range of -65 C to +125 C and complies with MIL-DTL-55302 standards.
