1.RATED VOLTAGE
Please consider the following information when selecting and using capacitors.
Specifications, materials and so on in the catalog may be subject to change without notice.
Data in the catalog is not guaranteed value, but typical value only.
ORDERING INFORMATION
Please confirm and inform us of the following information when ordering capacitors.
Working voltage : AC or DC
Capacitance and capacitance tolerance
Operating temperature range
Special operating condition : waveform, effective value,crest value, frequency, pulse, etc.
Expected failure mode : Influence to other components, when the capacitor gets failure, or influence to the capacitor,
when the other component or the circuit works irregularly.
Soldering condition
Operating environmental condition
Others
Ask for our technical specifications of the capacitor and confirm it to be suitable for the application before purchase
and/or use.
PROPER USE INFORMATION
Rated voltage is the maximum peak voltage (sum of D.C. voltage and peak A.C. voltage which is no more than the value
specified in the individual specification) which may be applied to a capacitor continuously at its rated temperature.
Rated voltage of capacitors for electronic equipment is usually DC voltage. (Unless otherwise specified)
When a D.C. rated capacitor is used in an A.C. circuit, the capacitor generates heat except for an across the line
capacitor. We recommend using capacitors below the voltage shown in Table 1.

FILM CAPACITORS
Rated voltage derating by category temperature
Use of the capacitors at high temperature shortens the capacitor life due to thermal deterioration. When operating
capacitors at high temperature, please derate the operating voltage in conformance with the graphs below. (Fig1∼2)
Rated voltage derating by high frequency
Using a capacitors at high frequency will shorten its life due to the generation of heat. When operating capacitors at high
frequency, please reduce the operating voltage according to specification sheet.
Use in special wave form
If you want to use the capacitor with a special wave-form other than a sine wave, please inquire to us for details after
identifying the wave-form with which the capacitor is required to be used, because the effective value varies with
wave-form.
(NOTE) Where a DC bias is voltage included,the DC rated voltage minus the DC bias voltage becomes the permissible AC
voltage, and this AC voltage shall be derated depending on the frequency.
PERMISSIBLE CURRENT FOR FREQUENCY
When using capacitors with an alternating current, effective current should not exceed the value of permissible current for
frequency shown in the graph of each series.(individual page)
