BASIC TEST AND ENVIRONMENTAL RELIABILITY TEST
Humidity
The specimen shall be subjected to 40+/-2°C, 90 to 95% R.H.
For 1000 hours without load and then stored at room
temperature and normal humidity for 1 to 2 hours. Thereafter,
the change of Vn shall be measured and meet the requirement
of:
∆ Vn/Vn≤ ± 5%.
Impulse life
The impulse current listed on catalog is applied 1000 times
continuously with the interval of 30 seconds at room
temperature. The change of Vn shall be measured
∆ Vn/Vn≤ ± 10%
Low temperature
The specimen shall be subjected to 40 ±2°C without load for
1000 hours and then stored at room temperature and normal
humidity for 1 to 2 hours. Thereafter, the change of Vn shall be
measured and meet the requirement of ∆ Vn/Vn ≤± 5%.
High temperature load
After being continuously applied the maximum allowable
Voltage at 85 ±2°C for 1000 hours, the specimen shall be
stored at room temperature and humidity for 1 to 2 hours. The
change of Vn shall be measured and meet the requirement of
Vn/Vn ≤± 10%.
High temperature storage
The specimen shall be subjected to 125 ±1°C for 1000 hours. In
a drying oven without load stored at room temperature and
humidity for 1 to 2 hours. The change of Vn shall be measured
and meet the requirement of ∆ Vn/Vn ≤± 5%.
Withstanding Voltage
The specified voltage shall be applied between both terminals
of the specimen connected together for 1 minute, with no
remarkable mechanical damage.

Terminal bending strength
The unit shall be secured with its terminal kept vertical and the
weight specified above shall be applied in the axial direction.
The terminal shall gradually be bent 90° in one direction, then
90° in the opposite direction, and again back to the original
position. A bend of lead wire shall be repeated 2 times, with no
remarkable mechanical damage.
Loading weight in bending strength
5N (0.51Kg)
5N (0.51Kg)
10N (1.02Kg)
Vibration
Subjected to simple harmonic motion of 0.75 mm amplitude 1.5
mm maximum total excursion between limits of 10-55 Hz.
Frequency scan shall be traversed in one minute. This motion
shall then be applied for period of 2 hours in each of three
mutually perpendicular directions, with no remarkable
mechanical damage.
Solderability
After dipping the terminal to a depth of approximately 3mm from
the body in a soldering bath of 235 ±5°C for 2 ±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 with
temperature of 260 ±5°C to a point of 2~2.5 mm from the body
of the unit, be held there for 10 ±1 sec (5N series: 5 ±1 sec) and
then be stored at room temperature and humidity for 1 to 2
hours. The change of Vn shall be measured and meet the
requirement of ∆ Vn/Vn ≤ ± 5% with no remarkable mechanical
damage.
Damp heat load
The specimen shall be subjected to 40 ±2°C, 90 to 95% R.H.
and the maximum allowable voltage for 100 hours and then
stored at room temperature and normally humidity for 1 to 2
hours. The change of Vn shall be measured and meet the
requirement of
∆ Vn/Vn ≤ ± 10%.
Temperature cycle
The temperature cycle is repeated fives cycles with
(1)-40 ±3°C keeping 30 ±3 minutes then (2) room temperature
keeping 15 ±3 minutes then (3)125 ±2°C keeping 30 ±3 minutes
then (4) room temperature keeping 15 ±3 minutes and then
stored at room temperature and humidity for 1 to 2 hours. The
change of Vn shall be measured and meet requirement
∆ Vn/Vn ≤ ± 5% with no remarkable mechanical damage.
