The 142-1000-033 is a 50 Ohm, hermetically sealed SMK (2.92mm) feedthrough connector. It operates over a broad frequency range from DC to 40 GHz with a nominal impedance of 50 Ohms and a maximum insertion loss of just 0.2 dB at 40 GHz. Key electrical characteristics include a working voltage of 250 VRMS and a dielectric withstanding voltage of 500 VRMS at sea level. Designed for robust performance in harsh environments, this component features a hermeticity rating of 1x10⁻⁸ cc/sec and a wide operating temperature range from -55°C to +165°C. Its Kovar construction with gold plating and compliance with MIL-STD-202 for solderability make it ideal for critical applications requiring a reliable RF signal path through a sealed enclosure.
