Specifications
Testing Method
Standard test
conditions
Electrical characteristics shall be measured under the following conditions.
Temp. : 5 to 35 °C, Relative humidity : 85 % or less
Varistor voltage
To meet the specified
value.
The Varistor voltage is the voltage (VC,or VcmA) between both end terminals of a
Varistor when specified current (CmA) is applied to it. The measurement shall be
made as quickly as possible to avoid heating effects.
Maximum
allowable voltage
To meet the specified
value.
The maximum DC voltage that can be applied continuously to a varistor.
Capacitance
To meet the specified Capacitance shall be measured at the specified frequency, bias voltage 0 V,
value.
and measuring voltage 0.2 to 2 Vrms.
Maximum peak
current
To meet the specified
value.
The maximum current measured (Varistor voltage tolerance is within ±10 %)
when a standard impulse current of
8/20 µ seconds is applied twice with an interval of 5 minutes.
Maximum ESD
To meet the specified
value.
The maximum ESD measured (while the varistor voltage is within ±30 % of its
nominal value) when exposed to ESD 10 times
(five times for each positive-negative polarity) based on IEC61000-4-2.
