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 speciï¬ed
value.
The Varistor voltage is the voltage (VC,or VcmA) between both end terminals of a
Varistor when speciï¬ed 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 speciï¬ed
value.
The maximum DC voltage that can be applied continuously to a varistor.
Capacitance
To meet the speciï¬ed Capacitance shall be measured at the speciï¬ed frequency, bias voltage 0 V,
value.
and measuring voltage 0.2 to 2 Vrms.
Maximum peak
current
To meet the speciï¬ed
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 speciï¬ed
value.
The maximum ESD measured (while the varistor voltage is within ±30 % of its
nominal value) when exposed to ESD 10 times
(ï¬ve times for each positive-negative polarity) based on IEC61000-4-2.
Solder ability
The part shall be immersed into a soldering bath under the conditions below.
Solder: H63A
