SVC101D-07A

Manufacturer Part Number
SVC101D-07A
Description
SVC Varistors Type
Manufacturer
SAMWHA [SAMWHA ELECTRIC]
Datasheet
Capacitance
Typical values measured at a test frequency of 1kHz
Rated peak transient current : itm
Maximum peak current through the varistor with line voltage
applied.
The maximum peak current with in the varistor voltage change
ratio of ±10% with the standard 8/20㎲ impulse current applied
two times at 5 minute interval.
Rated transient energy : Wtm
Maximum allowable energy for a single impulse of 2ms
square-wave current waveform with rated continuous voltage
applied. Maximum energy rating base on a shift of Vnom of
less than ±10% of initial value.
Pulse lifetime rating
This is expressed as the maximum allowable number of
impulse currents applied.
8/20㎲ impulse current(or 2ms square wave) is applied at
prescribed interval.
This curve also provides for derating current as required with
repetitive pulsing.

Test current waveform
Characteristics tests for Varistors are carried out by using 8/20㎲
test impulses Data such as the maximum clamping
voltage(Vc)and the transient peak current(Itm) are obtained by
using this impulse current
However, for the Vc characteristics of the Axial Package type a
10mA DC squarewave current is used to cary out the test.
Rated RMS Voltage : Vacm
Maximum continuous sinusoidal RMS voltage at 50/60Hz which
may be applied.
Rated DC Voltage : Vdcm
Maximum continuous DC voltage which may be applied.
Rated average power dissipation : Ptam
Maximum average power that can be applied within the
specified ambient temperature.
