1.2.2.7.1. Two-Terminal Decoupling Capacitors

The decoupling capacitors section contains the default ESR and ESL values for the various two-terminal capacitors in the following footprints:
  • 0201
  • 0402
  • 0603
  • 0805
  • 1206
You also have the option to either modify the default values or enter your own commonly used custom values in the Custom field. If you are using a capacitor with a footprint that is not available in the tool, you must use the Custom field to enter the capacitor parasitics and the corresponding mounting inductance.

The decoupling capacitors section also provides the option for user-defined capacitors (such as User1 through User4). You can define the ESR and ESL parasitics for the various footprints and enter the corresponding capacitor value in the System_Decap tab. Choose the corresponding footprint when defining the capacitor values.
