Varistors have a high natural (non operating impedance) during normal standby use. A varistor”s impedance drops rapidly when subjected to a high voltage spike clamping the voltage to an acceptable level absorbing the unwanted energy thus protecting voltage sensitive components.
High energy absorption; excellent voltage clamping characteristics ; fast response ; low idle power and high surge current capability.
Protection of all types of semi conductor; suppression of switching transients; voltage clipping and circuit damping; absorption of surge voltages associated with lightening strikes; prolongation of contact life and the protection of industrial switching circuits.
