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. 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 use. It is essential to give consideration when to install a protective circuit at the design stage.
