Discrete capacitors deviate from the ideal capacitor. An ideal capacitor only stores and releases electrical energy, with no dissipation. Capacitor components have losses and parasitic inductive parts. These imperfections in material and construction can have positive implications such as linear frequency and temperature behavior in class 1 ceramic capacitors. Conversely…

The capacitor self-resonant frequency causes your capacitor to stop behaving like a real capacitor and start behaving more like an inductor at high frequency. This important effect is unnoticeable at low frequencies, but it becomes a major problem related to signal integrity, power integrity, and impedance matching at high frequencies.
Superior Voltage Resistance Characteristics The capacitor and coil resonate, reducing the impedance of the resonant circuit and allowing a large current to flow, resulting in a large voltage being applied to the capacitor.
