DESIGN NOTE
Varistors do not have an endless lifetime. Also a well dimensioned varistor may fail due to enormous
overload. This will result in heating, smoke emission and / or displosion of varistor itself. Therefore we
recommend to place varistors separate within a box on PCB.
Furthermore a fuse should be in the varistor’s current path to avoid
secondary current in case the varistor fails. This fuse can protect
against secondary currents and therewith caused damages.
