(1) Note: 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 should
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.
