Definition |
Finger Width |
The thickness of the finger. |
Finger Spacing |

Overlap |
The length of the finger from the open end of one finger to the open end of the adjacent finger. The Finger Length = Overlap + End Gap. |
End Gap |
The distance between the terminal and the finger. |
Number of Finger Pairs |
Number of finger pairs present in the capacitor. The example above has 4 finger pairs. |
Terminal Width |
The width of the terminal which is measured from the outer edge of the capacitor to the beginning of the End Gap. There is a terminal on both sides of the capacitor. |
