Capacitor Filter C-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.
A Complete Guide to Capacitors
A ceramic capacitor is encapsulated with two leads that emanate from the bottom then form a disc. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. In ceramic capacitors, a relatively high capacitance is achievable in a small physical size because of its high dielectric constant.
