How to find the right ceramic capacitor

In fact, this is a wrong concept. Due to the parasitic inductance of the capacitor, resonance occurs at a certain frequency point on the capacitor discharge loop. At the resonance point, the impedance of the capacitor is small, so the impedance of the discharge loop is minimum, and the effect of supplemental energy is also best. However, when the frequency exceeds the resonance point, the impedance of the discharge loop starts to increase, which means that the capacitance-providing current capability starts to decrease. The larger the capacitor's capacitance, the lower the resonant frequency, and the smaller the frequency range over which the capacitor can effectively compensate for current. So of course it is a tested capacitor. Safety certified ceramic capacitors are the best choice.

Ceramic capacitors as the external components of the device, almost every device data sheet, more clearly specify the selection parameters of the external components, that is, based on this to obtain the basic device selection requirements, further refinement and refinement. When selecting a ceramic capacitor, it is not only to look at the capacity and the package, but also depends on the environment in which the product is used. Special circuits must use special ceramic capacitors.
