Test Methods and Results
Items
Test Method
Standard
DC Spark-over
Voltage
Measure starting discharge voltage (Vs) by
gradually increasing applied DC voltage. Test
current is 0.5mA max. And the DC voltage
ascends up within 100V/s(Vs＜1000V) or
500V/s(Vs≥1000V).
Meet specified value.
Insulation
Resistance
Measure the insulation resistance across the
terminal at regular voltage. But the test voltage
doesn’t over the DC spark-over voltage.
Capacitance
Measure the electrostatic capacitance by
applying a voltage of less than 6V (at 1KHz)
between terminals.
Static Life
10KV with 1500pf condenser is discharged
through 0Ω resistor. 200 times at an interval of
10sec.
Rate-of-change, within ±30%
insulation resistance & capacitance,
conformed to rated spec.
Surge Current
Capacity
1.2/50μs & 8/20μs, 1000A, electrically
connected with a resistor (1~2Ω), ±5 times,
each time interval 60 seconds. Thereafter,
outer appearance shall be visually examined.
No crack and no failures
Cold Resistance
Measurement after -40℃/1000 HRS & normal
temperature/2 HRS.
Features are conformed to rated
spec.
Heat Resistance
Measurement after 125℃/1000 HRS & normal
temperature/2 HRS.
Humidity Resistance
Measurement after humidity 90~95℃(45℃)
/1000 HRS & normal temperature/2 HRS.
Temperature Cycle
10 times repetition of cycle -40℃/30min
→normal, temp/2 min →125℃/30min,
measurement after normal temp/2 HRS.
Solder Ability
Apply flux and immerse in molten solder
230±5℃ for 3sec up to the point of 1.5mm
from body. Check for solder adhesion.
Lead wire is evenly covered by
solder.
Solder Heat
Measurement after lead wire is dipped up to
the point of 1.5mm from body into 260±5℃
solder for 10sec.
Conformed to rated spec.

1) Time shown in the above figures is measured from the point when chip surface reaches temperature.
2) Temperature difference in high temperature part should be within 110℃.
3) After soldering, do not force cool, allow the parts to cool gradually.
Hand Soldering
Solder iron temperature: 350±5℃
Heating time: 3 seconds max.
General attention to soldering
● High soldering temperatures and long soldering times can cause leaching of the termination, decrease in
adherence strength, and the change of characteristic may occur.
● For soldering, please refer to the soldering curves above. However, please keep exposures to temperatures
exceeding 200℃ to fewer than 50 seconds.
● Please use a mild flux (containing less than 0.2wt% CI). Also, if the flux is water soluble, be sure to wash
thoroughly to remove any residue from the underside of components that could affect resistance.
Cleaning
When using ultrasonic cleaning, the board may resonate if the output power is too high. Since this vibration
can cause cracking or a decrease in the adherence of the termination, we recommend that you use the
conditions below.
Frequency: 40kHz max.
Output power: 20W/liter
Cleaning time: 5 minutes max.
