The 112515-75 is a 75 ohm PCB-mount receptacle jack connector designed for RF and microwave applications. The connector features a brass body with nickel plating, a PTFE insulator, and a phosphor bronze contact pin with gold finish, ensuring reliable electrical performance and corrosion resistance. Key electrical characteristics include a maximum VSWR of 1.15 at 3 GHz, indicating excellent impedance matching. The connector is designed for direct PCB mounting with two mounting holes (1.50 mm and 1.00 mm diameter) and is suitable for high-frequency signal transmission in telecommunications, test equipment, and RF systems where impedance control and low reflection are critical.
