What is an RC Filter?
RC Filters RC Filters are easily selectable electronic components designed to prevent or substantially minimize the occurrence of arcing and noise generation in relay and switch contacts. RC Filters consist of specially designed capacitors and resistors connected in series. Spark discharges and induced noise are absorbed over a wide range by the accumulation characteristic and impedance of the capacitor, while the RC time constant delays and averages surge voltage and oscillations. RC Filters must have the capacity to store surge voltages and current energy and afford protection against inductively induced potentials. The dielectric material in capacitors, used in RC Filters, affords a very high degree of voltage withstand strength. All resistors are non-inductive types to ensure a high degree of protection against pulse potentials.
