Design Kit WE-VS SMT Varistors

Comments

  • 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 used in the varistor’s current path, which trips when varistor is destroyed. This fuse avoids secondary currents and therewith caused damages.
