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 is X7R. However, depending on the application, X5R, Y5V and Z5U can also be used. (See Capacitor sections in

APPLICATION HINTS.)
