All electronic components or functional modules listed in this catalog are developed, designed and intended for
use in general electronics equipment.(for AV, office automation, household, office supply, information service,
telecommunications, (such as mobile phone or PC) etc.). Before incorporating the components or devices into any
equipment in the field such as transportation,( automotive control, train control, ship control), transportation signal,
disaster prevention, medical, public information network (telephone exchange, base station) etc. which may have
direct influence to harm or injure a human body, please contact Taiyo Yuden Co., Ltd. for more detail in advance.
Do not incorporate the products into any equipment in fields such as aerospace, aviation, nuclear control, subma-
rine system, military, etc. where higher safety and reliability are especially required.
In addition, even electronic components or functional modules that are used for the general electronic equipment,
if the equipment or the electric circuit require high safety or reliability function or performances, a sufficient reliabil-
ity evaluation check for safety shall be performed before commercial shipment and moreover, due consideration to
install a protective circuit is strongly recommended at customer's design stage.
