The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. Ceramic capacitors placed right at the input of the regulator are effective in achieving this.
To choose the right capacitor, consider the following factors: select a tolerance that meets your circuit's demands, ensure the capacitor's physical dimensions fit into your circuit design, and choose between through-hole and surface-mount capacitors based on your application.
The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors. Depending on what you are trying to accomplish, the amount and type of capacitance can vary.
Capacitor prices can vary from less than a cent to more than $100. The cost depends on various factors such as the type, voltage rating, and capacitance. When choosing a capacitor, consider your application and budget constraints.
The most important parameters for selecting output capacitors are the magnitude of the load transient (ΔI) and the distributed bus impedance to the load. The selection is determined by the allowable peak voltage deviation (ΔV), which should reflect the actual requirements.
It will also depend on the physical size requirement. The capacitor physical size is directly proportional to the voltage rating in most cases. For instance, in the sample circuit above, the maximum level of the voltage across the capacitor is the peak level of the 120Vrms that is around 170V (1.41 X 120V).

Variable Capacitor The factors to be looked at before choosing a capacitor are. Stability: The value of the capacitor changes with the time and temperature.
When a capacitor is fully charged or discharged, the impedance is infinite, i.e., it acts like an open circuit and does not allow current to pass. This means large capacitors take a long time on charging and discharging while small capacitors can quickly do this to act like an open circuit, not allowing the current to pass (high impedance ...
