The 145-0701-802 is an end launch jack connector designed for high-frequency RF/microwave applications. It features a 50-ohm impedance with a frequency range of 0 to 40 GHz and a maximum working voltage of 250 VRMS at sea level. The connector utilizes a stainless steel passivated main body, beryllium copper contacts with gold plating at the mating end, and ULTEM 1000 insulation at the mating end with TEFLON at the solder end, ensuring excellent electrical performance and durability. The screw-on mounting type (SWK 2.50 mm) with a mating torque of 7 to 10 inch-pounds provides secure mechanical connection, while the 500-cycle minimum durability rating and environmental compliance (operating temperature -40°C to +85°C, MIL-STD-202 thermal shock and corrosion testing) make it suitable for demanding aerospace, defense, and telecommunications applications.
