How to Calculate Filter Capacitor for Smoothing Ripple

Nominal capacitance and allowable tolerance of electrolytic capacitor
The basic unit of a electrolytic capacitor is Farah (F), but this unit is too large and is rarely used in field marking. Other unit relationships are as follows: 1F=1000mF 1mF=1000μF 1μF=1000nF 1nF=1000pF The deviation between the actual capacitance of the electrolytic capacitor and the nominal capacitance is called tolerance, and the accuracy is called within
