(1) Refer to the Application Information section for further information
(2) Due to the DC bias effect of ceramic capacitors, the effective capacitance is lower then the nominal value when a voltage is applied. This is why the capacitance is specified to allow the selection of the nominal capacitor required with the DC bias effect for this type of capacitor. The nominal value given matches a typical capacitor to be chosen to meet the minimum capacitance required.
(3) Effective inductance value at operating condition. The nominal value given matches a typical inductor to be chosen to meet the inductance required.
