A minor tradeoff is that monolithic ceramic capacitors can be microphonic (i.e., sensitive to vibration), and some types may even be self-resonant, with comparatively high Q, because of the low series resistance accompanying their low inductance. Disc ceramic capacitors, on the other hand, are sometime quite inductive, although less expensive.

Learn MorePer the specification, the capacitor is designed to survive an overvoltage of up to 125V for no more than 5 seconds with a charging current not exceeding 50mA. However, DWV is an indication of the overvoltage performance of an MLCC and is not meant to allow voltages higher than the rated voltage in an application.
Learn MoreLeakage is modeled as a relatively large-value resistor in parallel with the ideal capacitor in the lumped model. It arises from the fact that the dielectric materials used within the capacitor are not perfect insulators, and allow some amount of DC current to pass through the capacitor when a constant voltage is applied.

Learn MoreSelf-resonance is also important here because, if the system operates beyond a capacitor''s self-resonance frequency, a capacitor will "act" like it has a different value. In addition, other reactive components (e.g., inductors, chokes, or ferrites) will interact with the capacitor to create complicated coupled oscillations.
Learn MoreNot only the parameter design, but also the voltage and current stress of the resonant capacitor should be considered in the selection of the resonant capacitor. If the maximum input voltage is 390 V, the voltage stress is the effective voltage value, which can be calculated as 207 V. The effective current value calculated according to Eq.
