Zinc oxide varistor
1.Uses
Zinc oxide varistor is a sort of sensitive component which
resistance value can vary with the applied voltage , it is widely
used in electrical and electronic equipments to protect them from
damage of transient overvoltage and for surge absorption .
2.Features
Broad varistor voltage range :*8V to 1.8KV
Fast response to transient voltage (ns)
High great withstanding surge current
Excellent non-linearity voltage
Symmetric V-I characteristic
No following-on current
Long life
3.Range of application
Used in surge protection for IC , transistor , diode semiconductor
switch circuits .
Used in communication ,telemetering,electrical control and various
electronic equioments.
Suppress the instantaneous overvoltage caused by electromagnetic
valve and relay .
Suppress the instantaneous overvoltage caused by power supply.
Suppress the instantaneous overvoltage caused by electronic
circuits.
Lighting protection for various kingd of electronic appliances
.
4.Technical conditions
The zinc oxide varistor carry out standards of GB/T****3 ,
GB/T****4, GB/T*********7 and SJ/T**********9 .
Measurement conditions : for varistor of *5D,*7D,*0D,*4D,*0D series
, voltage across the varistor measured under 1mADC .
Varisor voltage : the voltage between two terminals with the
specified measureing current applied is expressed by letter V .
Maximum continuous operating voltage :the maximum sinusoidal RMS
voltage or maximum DC voltage that can be applied continuously in
the specified environmental temperature range .
Working ambient temperature : **0℃ ~
**5℃
Storage temperature range : **0℃ ~
***5℃
