The capacitor tolerance should be 30% or better over temperature. The full operating conditions for the application should be considered

when selecting a suitable capacitor to ensure that the minimum value of capacitance is always met. Recommended capacitor type is

X7R. However, dependent on application, X5R, Y5V, and Z5U can also be used. The shown minimum limit represents real minimum

capacitance, including all tolerances and must be maintained over temperature and dc bias voltage (See capacitor section in
