Smoothing capacitor value

WebFor example, if the power supply is 12 volts, use a 25 volt or 40-volt Capacitor. For smoothing purposes, it is better to take a high-value capacitor like 1000 uF to remove the ripples of AC almost completely. In the power supply of Audio circuits, it is better to use a 2200 uF or 4700 uF capacitor since the ripples may create hum in the circuit. http://www.learningaboutelectronics.com/Articles/What-is-a-smoothing-capacitor
