Electrical characteristics shall be measured at following conditions
(Temperature: 5 to 35 °C, Humidity: Max. 85 %).
The voltage between two terminals with the specifi ed measuring
current CmA DC applied is called V
shall be made as fast as possible to avoid heat affection.
The maximum sinusoidal wave voltage (rms) or the maximum DC
voltage that can be applied continuously.
The maximum voltage between two terminals with the specifi ed
standard impulse current (8/20 µs).
The maximum power that can be applied within the specifi ed
ambient temperature.
The maximum energy within the varistor voltage change of ±10 %
when one impulse of 2 ms is applied.
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.
The maximum current within the varistor voltage change of ±10 %
with the standard impulse current (8/20 µs) applied one time.
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.
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.
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.
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.
change of Vc and mechanical damage shall be examined.
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.
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 fi ve
times and then stored at room temperature and humidity for
one to two hours. The change of Vc and mechanical damage
shall be examined.
After being continuously applied the Maximum Allowable Voltage
at 85±2 °C for 500 hours, the specimen shall be stored at room
temperature and humidity for one to two hours. Thereafter, the
change of Vc shall be measured.
