INFORMATION ON THE GENERAL CATALOG
REMINDERS
■ Please contact Taiyo Yuden Co., Ltd. for further details of product specifications as the individual
specification is available.
■ Please conduct validation and verification of products in actual condition of mounting and operating
environment before commercial shipment of the equipment.
■ 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, submarine 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 reliability 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.
