Resonant capacitor

Resonant capacitor

A resonant capacitor is an acoustics and electrical engineering term for a frequency resonant inductor. Although they are actually inductors, they are called capacitors because they are capable of storing significant amounts of charge (electrons) in an electrical network (circuit) whereas an inductor stores energy in a magnetic field. Resonant capacitors are typically used to introduce resonant frequencies of a given base frequency to spread signal energy over the frequency spectrum, effectively reducing the energy at the base frequency and increasing tolerance to EMI, Above about the Resonant capacitor information content.
