346-41-143-41-013000

Headers, Receptacles, Female Sockets Overview

The Mill-Max Manufacturing Corp. part number 346-41-143-41-013000 is a rectangular connector belonging to the 346 series, designed as an IC or transistor socket. It features a single row of 43 positions with a 0.100-inch (2.54mm) pitch spacing. The component utilizes press-fit termination for through-hole mounting and includes compliant tail pins that conform to plated through-holes without stressing multilayer board inner layers. Mating contacts are constructed from beryllium copper with a gold plating thickness of 30.0µin (0.76µm), while contact posts are made of copper alloy with tin plating at 200.0µin (5.08µm). The housing material is PCT polyester, rated UL94 V-0, supporting operation between -55°C and 125°C with a 3A current rating.
