■ 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, 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.

■ The contents of this catalog are applicable to the products which are purchased from our sales ofﬁces or distribu-

tors (so called“TAIYO YUDEN’s ofﬁcial sales channel”).

It is only applicable to the products purchased from any of TAIYO YUDEN’s ofﬁcial sales channel.

RING VARISTORS

■ FEATURES

■ APPLICATIONS

◦ꢀUse of strontium titanate semiconductor ceramics.

◦Eꢀ liminates sparks between governor contact and commutator and

brushes; absorbs noise in micro motors.

◦ꢀLarge net voltage non-linear coefficient ( α ) of 3 to 7, and large

electrostatic capacitance of 10 to 150 nF. Noise can thus be

absorbed over a wide range of frequencies.

◦ꢀSurface electrode type/Side mount electrode type

■ PRECAUTIONS

RING VARISTORS

1. Circuit Design

◆Veriﬁcation of operating environment, electrical rating and performance

1.A malfunction in medical equipment, spacecraft, nuclear reactors, etc. may cause serious harm to human life or have severe social ramiﬁcations. As such,

any varistors to be used in such equipment may require higher safety and/or reliability considerations and should be clearly differentiated from components

used in general purpose applications.

◆Operating Environment precautions

1.Varistors should not be used in the following environments :

Precautions

（1）Environmental conditions to avoid

a.exposure to water or salt water.

b.exposure to water or salt water.exposure to moisture or condensation.

c.exposure to corrosive gases (such as hydrogen sulﬁde, sulfurous acid, chlorine, and ammonia).

2. Soldering

Precautions

◆Soldering

・Be sure to do pre-heating sufﬁciently so that the difference between a soldering iron and ring varistors in temperature should be 150℃ or less.

・Ring Varistors are susceptible to thermal shock when exposed to rapid or concentrated heating or rapid cooling. Therefore, the soldering process must be

conducted with a great care so as to prevent malfunction of the components due to excessive thermal shock.

・Use a 30W soldering iron with a maximum tip diameter of 3.0mm.

・The soldering iron should not directly touch the products.

Technical ◆Soldering

ations

Refer to individual speciﬁcations.
