Capacitors

22.1 Symbols

There are mainly three symbols for capacitors:

These symbols are functionally equivalent. A capacitor is a more or less symmetrical two pins component. In ICs, non symmetry mainly results from parasitic components. This is the reason why two symbols out of three are not symmetrical.

22.2 Layout

Actual layout depends on actual capacitor type. Standard capacitors are rectangular with a body and connections through contacts at each end:
