This electronic component has been designed and developed for usage in general electronic equipment. Before incorporating this component into any equipment where higher safety and
reliability is especially required or if there is the possibility of direct damage or injury to human body, for example in the range of aerospace, aviation, nuclear control, submarine,
transportation, (automotive control, train control, ship control), transportation signal, disaster prevention, medical, public information network etc, Würth Elektronik eiSos GmbH must be
informed before the design-in stage. In addition, sufficient reliability evaluation checks for safety must be performed on every electronic component which is used in electrical circuits that
require high safety and reliability functions or performance.
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 secondaty currents
