Caution(Rating)
1. Operating Voltage
When DC-rated capacitors are to be used in AC or ripple current circuits, be sure to maintain the Vp-p Value of the
applied voltage or the Vo-p which contains DC bias within the rated voltage range.
When the voltage is applied to the circuit, starting or stopping may generate irregular voltage for a transit period
because of resonance or switching. Be sure to use a capacitor with a rated voltage range that includes these
irregular voltages.
2. Test condition for AC withstanding Voltage
(1) Test Equipment
Tests for AC withstanding voltage should be made with equipment capable of creating a wave similar to a 50/60
Hz sine wave. If the distorted sine wave or overload exceeding the specified voltage value is applied, a defect
may be caused.
(2) Voltage applied method
The capacitor's leads or terminals should be firmly connected to the output of the withstanding voltage test
equipment, and then the voltage should be raised from near zero to the test voltage. If the test voltage is applied
directly to the capacitor without raising it from near zero,it should be applied with the
*zero cross. At the end of the test time, the test voltage should be reduced to near
zero, and then the capacitor's leads or terminals should be taken off the output of the
withstanding voltage test equipment. If the test voltage is applied directly to the
capacitor without raising it from near zero, surge voltage may occur and cause a
defect.
*ZERO CROSS is the point where voltage sine wave
(3) Dielectric strength testing method
In case of dielectric strength test, the capacitor’s is applied between the terminations for 1 to 5 sec., provided the
charge/discharge current is less than 50mA.
3. Soldering
If a chip component is heated or cooled abruptly during soldering, it may crack due to the thermal shock. To
prevent this, follow our recommendations below for adequate soldering conditions. Carefully perform preheating
so that temperature difference (ΔT) between the
solder and component surface is in the following
range. The smaller the temperatures difference (Δ
T) between the solder and component surface is,
the smaller the influence on the chip is.
