Ideal Common Mode Inductor

The Ideal Common Mode Inductor is a magnetically coupled four-terminal component.  Magnetic coupling is 100% so the voltage across the upper windings is equal to the voltage across the lower windings.  The number of turns is equal, upper and lower.  Impedance across the inductor windings is proportional to frequency.  Impedance increases with increasing frequency for all frequencies.

The Ideal Common Mode Inductor is available for series schematic diagram components.  Since the Ideal Common Mode Inductor is a four-terminal component it occupies two series component positions simultaneously.  If another component already exists in either series component position it will be replaced by the Ideal Common Mode Inductor.

To calculate and graph the impedance of the Ideal Common Mode Inductor component over the frequency range selected on the Frequency Range form, click the Graph button on the Component Library form toolbar or select menu Tools | Graph.

To change the Ideal Common Mode Inductor value, select the present value, enter the desired value, and click the OK button.  When the OK button is clicked the Ideal Common Mode Inductor is placed on the schematic diagram.  If the Close button is clicked the Component Library form closes with no changes to the schematic diagram.
