The 142-1000-002 is a 50 Ohm hermetically sealed feedthru connector designed for high-frequency signal transmission. It features a nominal impedance of 50 Ohms and operates over a frequency range from DC to 26.5 GHz. The construction includes a Kovar outer ring and pin, both with a minimum of .00005 inches of gold plating over nickel, and a Corning 7070 glass insulator for a robust hermetic seal. This feedthru has a working voltage of 250 VRMS, a dielectric withstanding voltage of 500 VRMS, and a minimum insulation resistance of 5000 Megohms. With an operating temperature range of -55°C to +165°C and a hermeticity rating of 1x10⁻⁸ at one atmosphere, it is ideal for demanding applications requiring a reliable, sealed connection in harsh environments.
