“ZNR” Transient/Surge Absorbers (Type E) “ZNR” Transient/Surge Absorbers Type :
E
The ZNR Type E is capable of handling larger surge energy than Type D in applications to protect electronic equipment or semiconductor devices from switching and induced lightning surges.
Features ● Very large surge withstanding capability with a compact size ● Direct mounting on boards like a power distribution board available ● Fast response to steep impulse voltage ● Low clamping voltage for better surge protection ● RoHS compliant
Recommended Applications ● Transistor, diode, IC, thyristor or triac semiconductor protection ● Surge protection in industrial power plant operations ● Relay or electromagnetic valve surge absorption ● Surge absorption applications in broadcasting, communications devices, traffic/railroad, agricultural facilities, waterworks ● Surge protection of automatic control devices for power distribution line
Note : Ask our factory for Product Specification before use.

Varistor Voltage
The voltage between two terminals with the specified measuring current CmA DC applied is called Vc or VCmA. The measurement shall be made as fast as possible to avoid heat affection.
Maximum Allowable Voltage
The maximum sinusoidal wave voltage (rms) or the maximum DC voltage that can be applied continuously.
Clamping Voltage
The maximum voltage between two terminals with the specified standard impulse current (8/20 μs).
Rated Power
The maximum power that can be applied within the specified To meet the ambient temperature. specified value.
Energy
The maximum energy within the varistor voltage change of ±10 % when one impulse of 2 ms is applied.
