BASIC TEST AND ENVIRONMENTAL RELIABILITY TEST
Humidity
Terminal bending strength
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:
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 dir ection, then
90°in the opposite direction, and again back to th e original
position. A bend of lead wire shall be repeated 2 times, with no
remarkable mechanical damage.
∆ Vn/Vn≤ ± 5%.

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%
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.
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
Solderability
After being continuously applied the maximum allowable
Voltage at 85 ±2°C for 1000 hours, the specimen sha ll 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%.
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
High temperature storage
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.
The specimen shall be subjected to 125 ±1°C for 100 0 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.
Damp heat load
The specimen shall be subjected to 40 ±2°C, 90 to 9 5% 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
