(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 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.
