REMINDERS FOR USING THESE PRODUCTS
Before using these products, be sure to request the delivery specifications.
SAFETY REMINDERS
Please pay sufficient attention to the warnings for safe designing when using this products.
REMINDERS
⃝Please pay careful attention to the precautions and follow safe designing practices when using these products.
⃝Please observe the following precautions in order to avoid problems with chip varistors such as characteristic degradation and
element destruction
Please store these products in an environment with a temperature of 5 to 40°C and humidity level of 20 to 70%RH, and use
them within six months.
Poor storage conditions may lead to the deterioration of the solderability of the edge electrodes, so please be careful to avoid
contact with humidity, dew condensation, dust, toxic gas (hydrogen, hydrogen sulfide, sulfurous acid, chlorine, ammonia, etc.),
direct sunlight, and so on.
Please do not use products that have been dropped or detached when mounting.
Please solder with the reflow soldering method, and not the flow (dip) soldering method.
⃝Please observe the following precautions to avoid problems with varistors such as characteristic degradation and element
destruction, which ultimately lead to the generation of heat and smoke with the elements.
Do not use in locations where the temperatures exceed the operating temperature range such as under direct sunlight or near
sources of heat.
Do not use in locations where there are high levels of humidity such as under direct exposure to weather and areas where steam
is released.
Do not use in locations such as dusty areas, high-saline environments, places where the atmosphere is contaminated with
corrosive gas, etc.
Avoid powerful vibrations, impact (such as by dropping), pressure, etc. that may lead to splitting in the products.
Do not use with a voltage that exceeds the maximum allowable circuit voltage.
When resin coating (including modular) a varistor, do not use a resin that will cause deterioration of the varistor. Be sure never
to use resin that generates hydrogen as palladium is used for the inner electrode.
Avoid attachment near combustible materials.
⃝Please contact our sales offices when considering the use of the products listed on this catalog for applications, whose
performance and/or quality require a more stringent level of safety or reliability, or whose failure, malfunction or trouble could
cause serious damage to society, person or property (\qspecific uses\q such as automobiles, airplanes,medical instruments,
nuclear devices, etc.) as well as when considering the use for applications that exceed the range and conditions of this catalog.
⃝As range of catalog, conditions are transcended, or for damage that generated by was used in application specific, etc, accept
no the responsibility, wish.
⃝Please take appropriate measures such as acquiring protective circuits and devices that meet the uses, applications, and
conditions of the instruments and keeping backup circuits.
Please be sure to request delivery specifications that provide further details on the features and specifications of the products for proper and safe use.
Please note that the contents may change without any prior notice due to reasons such as upgrading.

■characteristics of chip varistor
■Equivalent circuit of chip varistors
Varistors are voltage dependent nonlinear resistive elements
with a resistance that decreases rapidly when the voltage is
over the constant value.
Varistors become zener diode of 2 serial connection and
equivalent, and does not have polarity.

Attention on a circuit board design
■Board design
When attached to chip varistors, amount of silver used (fillet
size) has direct impact on chip varistors after mounting.
Thus, sufficient consideration is necessary.
Set of land dimensions
(1) As the stress rises in the chip varistors owing to the increase
in silver, breakage and cracks will occur. Cause including
crack, as caution on board land design, configure the shape
and dimensions so that the amount of silver is appropriate.
If you installed 2 or more parts in the Common Land,
separated by a solder resist and special land of each
component.
(2) When peak levels panning-at soldering is excessive, by
solder contraction stress, mechanical-thermal stress causes
a Yasuku chip crack. In addition, when the peak level is
underestimated, terminal electrode fixed strength is
insufficient. This causes chip dropouts and may affect
circuit reliability. Representative example of the panning of
peak levels is shown in the following.
Recommended silver dose
Solder stress is increased,
and it is easy for a crack to
form.
Solder volume
overload
Most large serving amount
Minimum prime amount
Decent solder
volume
Fixed strength is weak, and
there is connection a
problem and risk of loss.
