The 2065-10-9 is a 75-ohm BNC connector manufactured by Winchester/Kings, designed for professional video and RF applications requiring high-frequency signal integrity. It operates across a frequency range of DC to 6 GHz with a nominal impedance of 75 ohms and is rated for a working voltage of 500 VRMS, delivering excellent return loss performance across the frequency spectrum (less than -30 dB up to 1.5 GHz, less than -22 dB up to 3.0 GHz, and less than -18 dB up to 6.0 GHz). The connector features a Teflon insulator, silicone rubber gasket, beryllium copper spring washer and outer contact, and commercial bronze K-grip sleeve, with gold-plated center contacts and tarnish-resistant nickel finish on other metal parts. It is compliant with the SMPTE 424M (3G-SDI) specification and is designed for use with Belden 1694A cable, making it ideal for broadcast video, professional audio/video systems, and high-frequency RF applications where signal fidelity and impedance matching are critical.
