How Do You Connect Electrolytic Capacitors For AC Operation?
An electrolytic capacitor is a specific capacitor that is generally used as a ripple filter in electrical power supplies. It is also used to couple alternating current (AC) signals across direct current (DC) potentials, or to filter low frequency signals in an electrical circuit. Typically with a capacitance value of over one micro-Farad (mF), the electrolytic capacitor’s most important characteristic is its polarity. Confirm the electrolytic capacitor’s proper voltage rating as specified for the circuit. When replacing an electrolytic capacitor in an older circuit where old and now unused values are cited, be careful to use newer electrolytic capacitors that have higher voltage rating values. Using those with lower-than-specified voltage ratings may result in an explosion. Confirm the proper capacitance value for the electrolytic capacitor. Note that electrical standards have changed and older capacitance values such as 15 mF and 50 mF, for example, have been replaced with 16 mF and 6
