Cornell Dubilier (CDE) QAS Arc Suppressor/Snubber Network Film Capacitors extend the operating life of electronic and electromechanical devices by reducing or eliminating electrical arcing, noise, and EMF. CDE QAS Film Capacitors feature relay contact protection and noise reduction on controllers and drives. The devices are coated with flame-retardant epoxy and include Spark Arc Suppression circuits (RC networks). QAS capacitors are designed to reduce arcing and noise generated and produced in switches, mechanical relays, and solid-state devices.
