The 3020-10-0300-00-TR is an IDC (Insulation Displacement Connector) box header designed for surface-mount technology (SMT) with 0.100" (2.54 mm) pitch spacing. It features a current rating of 3.0 A AC/DC and a voltage rating of 250 V AC/DC, with a maximum contact resistance of 20 mO and insulation resistance of 1,000 MO minimum. The connector withstands 600 V AC per minute and operates reliably across a temperature range of -40 °C to +105 °C. The insulator is constructed from high-temperature nylon 6T plastic (UL94V-0) in black, with copper alloy terminals finished in gold plating over nickel. This connector is ideal for industrial cable and connector applications requiring reliable board-level interconnection with excellent electrical performance and environmental durability.
