Interdigitated Capacitor
![Interdigitated Capacitor](/images/id-cap.gif)
This example is an interdigitated capacitor composed of seven closely coupled parallel lines. This capacitor has a nominal value of about 0.1 pF below 1 GHz. As the frequency increases, the capacitor becomes more capacitive, due to the increase in fringing fields between the fingers. This type of behavior is typical of microstrip interdigitated capacitors.
