The 3020-14-0300-00 is a 2.54mm pitch box header SMD type connector designed for surface-mount applications. It features a 14-pin configuration with a current rating of 3.0A AC/DC and voltage rating of 250V AC/DC, making it suitable for industrial and commercial electronic assemblies. The connector utilizes brass contacts with gold plating and a nylon (UL9494V-0) insulator body, providing excellent contact resistance of 20 ohm maximum and insulation resistance of 1,000M ohm minimum. With an operating temperature range of -40°C to +105°C and withholding voltage of 600V AC/minute, this connector delivers reliable performance in demanding environments. The RoHS-compliant design and SMD mounting capability make it ideal for automated PCB assembly processes, particularly in industrial control systems, telecommunications equipment, and power distribution applications.
