The minimum capacitance must be greater than 0.33 µF over the full range of operating conditions. The capacitor tolerance must be

30% or better over the full temperature range. The full range of operating conditions for the capacitor in the application should be

considered during device selection to ensure this minimum capacitance specification is met. TI recommends X7R capacitors; however,

capacitor types X5R, Y5V and Z5U may be used with consideration of the application and conditions.
