High Density BNC (HD BNC)
has retaining the electrical characteristics of the original specification, but has smaller footprints giving a higher packing density on circuit boards and equipment backplanes. The HD-BNC Connector has delivers both true 50 and 75 ohm performance in a footprint 4xs smaller than traditional BNC connectors. These connectors have true 50 and 75 ohm impedance making them suitable for HD video applications.
