Sizing Filter Capacitor for full wave rectifier
The downside of a larger than needed filter capacitor, is that the peak RMS current is higher through the transformer windings, giving more I²R loss and heat in the transformer. That high peak current is the reason a transformer current rating should be derated nearly 50% for a diode-capacitor DC supply current value.

How to Choose Capacitor Value to Filter Power Supply Noise?
The output rectifier is pulsating DC (fluctuating DC) rather than pure DC. To purify the output of the rectifier a filter is needed. The filters can be formed from capacitors. An appropriate value of the capacitor is required for the suppression of the ripple voltage. Use the following formula to choose a capacitor value to filter supply noise.

6 Frequently Asked Questions about “How to choose rectifier capacitor”
Which capacitor should be used for rectification?
For rectification, it requires most of the times a larger capacitance to get a near straight line voltage. Thus, the first option is to consider an electrolytic capacitor. In some applications that the ripple current is very high, electrolytic capacitor will not work anymore as its ripple current is smaller.
How does a capacitor work in a rectifier circuit?
The capacitors help to fill in the gaps in the rectified voltage. While the voltage reaches its highest values, the capacitor is charged. When it drops below a certain level, it discharges. However, due to the rectifier circuit, it cannot send the charge back to the voltage source, but discharges it via the consumer.
Do I need a larger capacitance to filter a rectified voltage?
Well, it depends to your application. If you are going to filter output a rectified voltage, then you need a larger capacitance for sure. However, if the capacitor is only intended to filter signal noise in a small signal circuit, then a small capacitance in pico to nano farads will do. So, know your application.
How to select capacitors?
Aside from the capacitance, another thing to consider on how to select capacitors is the tolerance. If your application is very critical, then consider a very small tolerance. Capacitors come with several tolerance options like 5%, 10% and 20%. It is your call which is which.
How to choose a film capacitor?
Thus, the first option is to consider an electrolytic capacitor. In some applications that the ripple current is very high, electrolytic capacitor will not work anymore as its ripple current is smaller. In this case, film capacitors are chosen as they are having very high ripple current rating.
What is the minimum capacitance needed for a C1 rectifier?
