1703403120

The Molex 1703403120 is a high-speed backplane connector from the Impact series, designed for differential pair signaling applications. This receptacle features 120 female socket positions organized into 12 rows and 10 columns, supporting 40 differential pairs. The connector uses a press-fit termination process for reliable solderless attachment to the PCB, with a right-angle orientation for board edge mounting.

The Impact guide left keying ensures accurate alignment during mating. Contacts are finished with 30 microinches of gold over nickel, providing excellent corrosion resistance and durability for repeated mating cycles. The gray housing is suitable for visual identification in dense backplane layouts. The connector is rated RoHS3 compliant and has an MSL of 1 (unlimited floor life) per available data.

This design is optimized for high-speed data transmission applications typical in telecom and data center equipment. Press-fit termination eliminates soldering process variability while maintaining reliable electrical connections. The right-angle mount is ideal for mezzanine and orthogonal backplane architectures where space constraints require perpendicular PCB placement.
