“ZNR” Transient/Surge Absorbers (Type CK)
UL and CSA Recognized
“ZNR” Transient/Surge Absorbers with Tabs
Type : CK
ZNR Transient/Surge Absorber with Tabs is a heavy duty
type ZNR with very unique tab terminals which bring forth
a higher reliability.
These tabs are used as electrical connecting terminals
and also its mounting legs. This type of ZNR is meant for
applications in power supplies or transient voltage surge
suppressor units where large surge current or high surge
energy absorption is required.
Features
● UL
and CSA recognized components
energy handling capability (210 to 750 joules)
● Large withstanding peak current (25 to 30 kA, 8/20 µs, 1 time)
● Common terminals for electrical connection and mounting
● RoHS compliant
● High
Recommended Applications
● Power suppliers for OA, FA, telecommunication
● Power strips
● Transient voltage surge suppressor units
or industrial equipment
Note : Ask our factory for Product Specification before use.

Characteristics
Electrical
Standard Test Condition
Mechanical
Specifications
Electrical characteristics shall be measured at following conditions
(Temperature: 5 to 35 °C, Humidity: Max. 85 %).
———
Varistor Voltage
The voltage between two terminals with the specified measuring
current 1mA DC applied is called V1 or V1mA. 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
ambient temperature.
Energy
The maximum energy within the varistor voltage change of ±10 %
when one impulse of 2 ms is applied.
Maximum
Peak
Current
Environmental
Test Methods/Description
2 times
The maximum current within the varistor voltage change of
±10 % with the standard impulse current (8/20 µs) applied
two times with an interval of 5 minutes.
1 time
The maximum current within the varistor voltage change of ±10 %
with the standard impulse current (8/20 µs) applied one time.
To meet the
specified value.
Robustness of
Terminations
(Tensile)
After gradually applying the force of 19.6 N (2 kgf) and keeping
the unit fi xed for ten seconds, the terminal shall be visually
examined for any damage.
No remarkable
damage
Vibration
After repeatedly applying a single harmonic vibration (amplitude:
0.35 mm): double amplitude: 0.7 mm with 1 minute vibration
frequency cycles (10 Hz to 55 Hz to 10 Hz) to each of three
perpendicular directions for 2 hours. Thereafter, the unit shall be
visually examined.
No remarkable
damage
Solderability
After dipping the terminal to a depth of approximately 3 mm from
the body in a soldering bath of 230±5 °C for 5.0±0.5 seconds,
the terminal shall be visually examined.
Approximately 95 %
of the terminals shall
be covered with new
solder uniformly.
Resistance to
Soldering Heat
The terminal shall be dipped into a soldering bath having a
temperature of 350±10 °C to a point 4.0±0.8 mm from the body
of the unit and then be held there for 3.0±0.5 seconds. The
change of Vc and mechanical damage shall be examined.
ΔV1mA /V1mA < ± 5 %
No remarkable
damage
Dry Heat/ High
Temperature
Storage
The specimen shall be subjected to 125±2 °C for 500 hours in a
thermostatic bath without load and then stored at room temperature
and humidity for one to two hours. Thereafter, the change of Vc
shall be measured.
Damp Heat/
Humidity
(Steady State)
The specimen shall be subjected to 40±2 °C, 90 to 95 %RH for
1000 hours without load and then stored at room temperature
and humidity for one to two hours. Thereafter, the change of Vc
shall be measured.
The temperature cycle shown below shall be repeated five
times and then stored at room temperature and humidity for
one to two hours. The change of Vc and mechanical damage
shall be examined.
