Test Methods and Results
Items
Test Method
Standard
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).
DC Spark-over Voltage
Rate-of-change, within±30%
insulation resistance & capacitance,
conformed to rated spec.
Measure the insulation resistance across the terminal
at regular voltage. But the test voltage doesn’t over
the DC spark-over voltage.
Insulation Resistance
Capacitance
Measure the electrostatic capacitance by applying a
voltage of less than 6V (at 1KHz) between terminals.
∣△Vs/Vs∣≤30%
10KV with 1500pf condenser is discharged through

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
u
u
u
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.
