Test Item |
Test Method |
Specification |
|
DC Spark-over Voltage Vs(V) |
Measure starting discharge voltage (Vs) by gradually increasing applied DC voltage. Test current is 0.5mA max. And the DC voltage ascends up within 500V/second. |
It depands on each spec. |
|
Insulation Resistance |
Measure the insulation resistance across the terminal at regular voltage. But the test voltage doesn't over the DC spark-over voltage. |
100MΩ min. |
|
Capacitance Cj(pF) |
Measure the electrostatic capacitance by applying a voltage of less than 6V (at 1KHz) between terminals. |
1pF max. |
|
Life |
10KV with 1500pf condenser is discharged through 0Q resistor. 200 times at an interval of 10sec. |
DC spark-over voltage JSE: | △ Vs/Vs | ≤30% |
|
Surge Current Capacity |
1.2/50卩s & 8/20ps. 3000A, electrically connected with a resistor (4~6 Ω), ±5 times, each time interval 60 seconds. Thereafter outer appearance shall be visually examined. |
No crack and no failures |
|
Cold Resistance |
Measurement after -40°C /1000 HRS & normal temperature/2 HRS. |
Features are conformed to rated spec. |
|
Heat Resistance |
Measurement after 125°C /1000 HRS & normal temperature/2 HRS. |
|
|
Humidity Resistance |
Measurement after humidity 90*95 (45 C°C)/1000 HRS & normal temperature/2 HRS. |
|
|
Temperature Cycle |
10 times repetition of cycle -40 °C /30min→normal, temp/2 min→125°C /30min, measurement after normal temp/2 HRS. |
|
|
Solder Ability |
Apply flux and immerse in molten solder 230±5°C 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°C solder for 10sec. |
Conformed to rated spec. |
Hand Soldering
Solder iron temperature: 350 ± 5 °C
Heating time: 3 seconds max
General attention to soldering
1. High soldering temperatures and long soldering times can causeleaching of the termination, decrease in adherence strength, andthe change of characteristic may occur.
2. For soldering , please refer to the soldering curves aboveHowever , please keep exposures to temperatures exceeding 200 Cto fewer than 50 seconds.
3. Please use a mild flux ( containing less than 0. 2wt % CI ). Also , ifthe flux is water soluble, be sure to wash thoroughly to remove anyresidue from the underside of components that could affectresistance.
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°C
3 ) After soldering , do not force cool , allow the parts to cool gradually.
When using ultrasonic cleaning , the board may resonate if the output power is too high . Since this vibration can cause cracking or a decreasein 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.
