2.Measurement of Capacitance

1. Measure capacitance with the voltage and frequency specified in the product specifications.

 1-1. The output voltage of the measuring equipment may decrease occasionally when capacitance is high.
         Please confirm whether a prescribed measured voltage is impressed to the capacitor.
 1-2. The capacitance values of high dielectric constant type capacitors change depending on the AC voltage applied.
         Please consider the AC voltage characteristics when selecting a capacitor to be used in a AC circuit.

3.Applied Voltage

1. Do not apply a voltage to the capacitor that exceeds the rated voltage as called out in the specifications.

 1-1. Applied voltage between the terminals of a capacitor shall be less than or equal to the rated voltage.
    (1) When AC voltage is superimposed on DC voltage, the zero-to-peak voltage shall not exceed the rated DC voltage.
          When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage.
    (2) Abnormal voltages (surge voltage, static electricity, pulse voltage, etc.) shall not exceed the rated DC voltage.

Maximum possible applied voltage.)

 1-2. Influence of over voltage
         Over voltage that is applied to the capacitor may result in an electrical short circuit caused by the breakdown 
         of the internal dielectric layers .
         The time duration until breakdown depends on the applied voltage and the ambient temperature.

4.Type of Applied Voltage and Self-heating Temperature

1.Confirm the operating conditions to make sure that nolarge current is flowing into the capacitor due to the
    continuous application of an AC voltage or pulse voltage.
    When a DC rated voltage product is used in an AC voltage circuit or a pulse voltage circuit, the AC current
    or pulse current will flow into the capacitor; therefore check the self-heating condition.
    Please confirm the surface temperature of the capacitor so that the temperature remains within the upper limits
    of the operating temperature, including the rise in temperature due to self-heating. When the capacitor is
    used with a high-frequency voltage or pulse voltage, heat may be generated by dielectric loss.

<Applicable to Rated Voltage of less than 100VDC>
  1-1. The load should be contained to the level 

 

       such that when measuring at atmospheric

   

 

  

 

temperature of 25°C, the product's self-heating

  

     remains below 20°C and the surface

          temperature of the capacitor in the actual circuit 
          remains within the maximum operating 
          temperature.
