This F-Type Auto Terminating Coaxial Adapter features a built-in 75-ohm, 1/4 Watt terminating resistor. The resistor is engaged when F-Series plugs are inserted, providing signal termination. It is designed for signal level energy only and requires engagement of F-Series plugs to disable the terminating resistor between the outer shell and center conductor. All dimensions are for reference only.
