Headers, Receptacles, Female Sockets Overview

The Preci-Dip 310-83-121-01-754101 is a 21-position rectangular socket connector from the 310 series. It features a 0.100-inch (2.54mm) pitch and utilizes surface mount termination for board-to-board applications. The housing is constructed from black polybutylene terephthalate (PBT) reinforced with glass fiber, rated UL94 V-0 for flammability. Contacts are female sockets made of beryllium copper, plated with gold over nickel for mating surfaces and tin for column termination. Rated at 3A and 150V DC, it operates within a temperature range of -55°C to 125°C.
