The 142-0711-841 is an SMA end launch jack assembly used for terminating RF signals at the edge of a printed circuit board. This connector is engineered with a characteristic impedance of 50 Ohms and operates over a broad frequency range from DC to 18 GHz. It provides reliable electrical performance with a dielectric withstanding voltage of 1000 VRMS minimum and an insulation resistance of 5000 megohms minimum. Designed for durability with a rating of 500 mating cycles and an operating temperature range of -65°C to 165°C, it is well-suited for high-frequency test equipment, telecommunications hardware, and aerospace systems.
