“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 tran sient volt age
surge sup pres sor units where large surge cur rent or
high surge en er gy absorption is required.
■ Recommended Applications
● Power suppliers for OA, FA, telecommunication or
industrial equipment
● Power strips
● Transient voltage surge suppressor units
Note: Ask our factory for Product Speci cation before
use.
■ Handling Precautions and Minimum Quantity / Packing Unit
Please see Related Information
■ Features
● UL and CSA recognized components
● High 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

■ Performance Characteristics (Type CK)
Characteristics Test Methods/Description Specifi cations
Standard Test Condition Electrical characteristics shall be measured at following conditions
(Temperature: 5 to 35 °C, Humidity: Max. 85 %). ———
Electrical
Varistor Voltage
The voltage between two terminals with the specifi ed measuring
current CmA DC applied is called VC or VCmA. The measurement
shall be made as fast as possible to avoid heat affection.
To meet the
specifi ed value.
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 specifi ed
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
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.
Mechanical
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.
ΔVCmA/VCmA < ± 5 %
No remarkable
damage
Environmental
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.
ΔVCmA/VCmA < ± 5 %
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.
Temperature Cycle
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.
