(1) The minimum capacitance should be greater than 0.5 μF over the full range of operating conditions. The capacitor tolerance should be
30% or better over the full temperature range. The full range of operating conditions for the capacitor in the application must be
considered during device selection to ensure this minimum capacitance specification is met. X7R capacitors are recommended however
capacitor types X5R, Y5V and Z5U may be used with consideration of the application and conditions.
(2) This specification is verified by design.
