The Win Source Electronics part number 1057827-ESQ-122-44-G-T is a rectangular connector from the ESQ series, designed as an elevated socket with a pitch of 0.100" (2.54 mm). It features 66 positions across three rows and is suitable for board-to-board applications. The connector is constructed with a black liquid crystal polymer (LCP) insulator and phosphor bronze contacts, which are plated with 20 ¬µin (0.51 ¬µm) gold for mating and 3 ¬µin (0.076 ¬µm) gold for post contacts. This connector has a voltage rating of 550 VAC and a current rating of 5.7 A per contact when two pins are powered. It operates within a temperature range of -55 ¬8C to +125 ¬8C. The termination style is solder, and it utilizes a push-pull fastening type. The connector is packaged in tubes and is designed for through-hole mounting. It is important to note that the connector is not lead-free solderable and is intended for specific applications such as PC/104 connectors.
