CHARACTERISTICS OF CHIP VARISTOR
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.

B
(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.
