Filter Capacitor- Explained. A filter capacitor is a capacitor which filters out a certain frequency or range of frequencies from a circuit. Usually capacitors filter out very low frequency signals. These are signals that are very close to 0Hz in frequency value. These are also referred to as DC signals. How Filter Capacitors Work
Capacitor Filter C-Filter
Low-Pass Filter. Capacitors are critical to low-pass filters, where they provide capacitive reactance that is used to filter out high frequencies. Since capacitive reactance is inversely proportional to frequency, the output of a low pass filter is taken across the capacitor, which primarily drops low frequencies. High-Pass Filter

What are the Best Capacitors for Power Supply Filtering?
With the right capacitor (or capacitor bank), you''ll be able to dampen voltage ripple from your rectifier while ensuring a long lifetime. Although most subjects involving "filter capacitors" simply refer to the output capacitor on a rectifier, it can also refer to the capacitor on the output of a voltage regulator.
