Flow
Soldering

Gas removal will be
recommended to keep good
solderability at high density
mounting of components.
If land is too large in
comparison with the size of
terminal surface, part may be
ill-situated at solder melting.

Test Methods
Unless otherwise specified, electrical measurements (initial/after
tests) shall be conducted at temperature of 5 to 35°C, relative humidity
of 45 to 85% and atmospheric pressure of 860 to 1060 hPa.
The voltage between two terminals with the specified measuring
current CmA DC applied is called Vc or V
CmA
. The measurement
shall be made as fast as possible to avoid heat affection.
Specifications
______
Maximum Allowable
The recommended maximum sinusoidal wave voltage (rms) or the
maximum DC voltage that can be applied continuously.
Voltage
Maximum Clamping
The maximum voltage between two terminals with the specified
impulse current (8/20 µs).
Voltage
Rated Power
The maximum power that can be applied within the specified ambient
temperature.
Maximum energy at less than ±10% of varistor voltage change when
the standard impulse (2 ms) is applied one time.
Maximum current at less than ±10% of varistor voltage change when
impulse current (8/20 µs) is applied two times continuously with the
interval of 5 minutes.
