The measuring current is 1mA/1 second max. It depands on each spec. Insulation Resistance Measure the insulation resistance of two end of leadwire under the specified DC voltage. 100MΩ min. Capacitance Cj(pF) Measure the Electrostatic Capacitance under the test condition of 1KHz,DC 6V(max). 1pF max. Life(JSE) Apply a standard impulse voltage (8X20μsec)of 100A for 5 times with intervals of 30 sec., and then change the polarity of the surge and apply a impulse again. Then measure DC spark-over voltage, IR & Capacitance. DC spark-over voltage JSE:∣△ Vs/Vs ∣ ≤30% Life(JSE) Apply 10 KV voltage charged in 1500pF condenser and apply the current to the specimen,200 times at 10 seconds of intervals Insulation Resistance & Capacitance to meet the specified value. Appearance: No cracks or 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. Pull Strength Apply 0.5kg load for 10sec. Lead shall not pull out to snap. Flexural Strength Bend lead wire at the point of 2mm from body under 0.25 load and back to its original point. Repeat 1 time.

Recommended Soldering Conditions Flow Soldering Conditions Hand Soldering Solder iron temperature: 350±5℃ Heating time: 3 seconds max. General attention to soldering 1.High soldering temperatures and long soldering times can cause leaching of the termination, decrease in adherence strength, and the change of characteristic may occur. 2.For soldering, please refer to the soldering curves above. However, please keep exposures to temperatures exceeding 200℃ to fewer than 50 seconds. 3.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. 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. 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.
