This electronic component is designed and developed with the intention for use in general electronics
equipments.
Before incorporating the components into any equipments in the field such as aerospace, aviation,
nuclear control, submarine, transportation, (automotive control, train control, ship control),
transportation signal, disaster prevention, medical, public information network etc. where higher
safety and reliability are especially required or if there is possibility of direct damage or injury to
human body, Wurth Elektronik must be asked for a written approval.
In addition, even electronic component in general electronic equipments, when used in electrical
circuits that require high safety, reliability functions or performance, the sufficient reliability
evaluation-check for the safety must be performed before by the user before usage.
