10. ! Caution about safety in use
I. Operating range (voltage, current, operating temperature)
Use the capacitor within the specified limits listed below (a to b). Over rated conditions might cause deterioration,
damage, smoke and fire. Do not use capacitor beyond range of the condition.
a) Permissible voltage
• Rated voltage of this product is 250VDC. Use the capacitor within rated voltage.
• When used in AC applied circuit, less than 125Vrms. When used in a high frequency, less than 125Vrms
should be applied and current applied should be less than the value of permissible current in Fig.2-1, 2-2 in
page 15 to 16. The performance of high temperature loading is in accordance with number 10, on page 4. The
performance of moisture resistant loading is in accordance with number 9, on page 3. Not to be in connected
directly to Primary or AC line.
• Use the peak of pulse voltage applied the capacitor within the DC rated voltage.
b) Permissible current
• The permissible current must be considered by dividing into pulse current (peak current) and continuous
current (rms current). When using, therefore, make sure the both current are within the permissible values.
In the case that a continuous current value is able not to be measured, use the capacitor within 7.5°C as the
inherent temperature rise confirmed by the measuring method show in page 14.
• Continuous current should be within specified figure in Fig.2-1, 2-2. Contact us when the waveforms are
totally different from the sine wave.
• Pulse current should be within the figures calculated by Tab. 1. Use within 10000 cycles of pulse current.
When pulse current applied more than 10000 cycles, please consult us before use.
c) Operating temperature range
• It must be noted, however the operating temperature range is the surface temperature of the capacitor, not
the ambient temperature of the capacitor.
• In actual use, make sure the sum of the ambient temperature + own temperature rise value (Within specified
value), that is the capacitor surface temperature is within the rated operating temperature range.
• If there is cooling plate of the other part of any resistance heated to high temperature near the capacitor, the
capacitor may be locally heated by the radiation heat, exceeding the operating temperature range, and
smoking or firing may be caused. Check the capacitor surface temperature at the heat source side.
d) Protective means for safety should be provided in case the pulse and rms current may exceed the permissible
values due to abnormal action of elsewhere in the circuit.
Please consult in advance when capacitors are connected in parallel to supplement capacitance.

• When washing right after soldering, make sure the capacitor surface temperature is lower than 60°C.
• It is necessary to remove cleaner from P.W.B. by drying thoroughly after cleaning.
• Cleaner shall contain halogen with less than 0.1wt%, because in case of cleaning after mounting, halogen in
flux will dissolve into cleaner.
• Consult with our engineering section in advance when further information for cleaning solvent, conditions
are required.
VII. Storage and preservation
• It must be noted that the solderability of the external electrode may deteriorated when stored in an
atmosphere filled with moisture, dust, or a reactive oxidizing gas (hydrogen chloride, hydrogen sulfide,
sulfuric acid) .
• Avoid location with particularly high temperature and high humidity, and store in conditions not exceeding
35°C and 85%RH. Storage period limit is 6 months (use within 6 months).
• Consult with our engineering section in advance when require further conditions except for the above.
VIII. Operating environment
• Consult us when used for a long period in humid environments, because characteristic deterioration as low
insulation resistance and oxidized evaporated film may occur due to humidity absorbed with the passing of
the time.
• Avoid to use in a place of corrosive and oxidizing gas atmosphere (hydrogen chloride, hydrogen sulfide,
sulfuric acid etc.)
• Avoid use under the environment where water is generated to deteriorated the characteristic of the capacitor
when the adhesion of water (drop of water etc.) is generated in the capacitor.
• No dust should be permitted to remain on the surface of the product as this may cause electrical leakage.

Measuring method of inherent temperature rise
As shown in the drawing, attach a thermocouple to the capacitor surface with adhesive, and measure
The surface temperature and capacitor surface temperature while avoiding radiation heat from
peripheral parts. At this time, use a thermocouple with small thermal capacity (φ0.1 T wire), and to
avoid heat release to the board, lift the parts to be measure from the board by using lead wire or the
like, and install as shown in the drawing. To avoid effects of convention and wind, put the capacitor
into the box or the like, and measure in wind-free condition.
