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.
