is held by its body in such a manner that the axis of the
termination is vertical;a mass applying a force of the

11.CAUTION OF USING !
(1) Permissible Conditions
Please use component within the conditions specified under the clause 1-1,1-2,1-3 and 1-4. If it is used
exceeding the condition range, there is danger of degradation, damage, or combustion. Please do not use it
on the conditions beyond rating.
1-1.Permissible voltage
Applicable peak voltage (Vo-p) between the capacitor terminals must be within the rated voltage
(including pulse voltage).
Under AC voltage, such as the secondary circuit of power supply, please use the following voltage.
400VDC: Below 141VAC (400 Vp-p), 630VDC: Below 223VAC (630 Vp-p)
In addition, please do not use in the AC primary side.
1-2. Permissible pulse current (Ao-p)
Please use components within the set pulse current value calculated from Table 1. However, there may
be a case of thermal destruction caused by excessive self-heating, if continuous pulse current is
generated. If the pulse is applied for more than 1 second and the interval is less than 10 seconds, please
check that the value of a self-temperature rise is lower than the value of Fig. 4.
1-3. Permissible continuous current (Arms)
Please use it within the range shown on figure 5. In addition, please ask when there is no indication of the
capacity.
Under the operating condition where the capacitor surface temperature rises over 85 ℃ (including
temperature rise through self heat generation) please use it within the range shown on figure 3.
Temperature rise through self heat generation, under room temperature and no air circulation, must be
within the range shown on figure 4. (Surface temperature shown on figure 4 is the maximum capacitor
surface temperature under the operating conditions.)
Temperature rise through self heat generation is affected by the environmental temperature and by the
measuring method. (See page 11)
1-4.Operating temperature range
Maximum capacitor surface temperature (environmental + self temperature rise) must be within the
category temperature range shown on page 1.
Capacitors may be affected by the heat radiated from heat-sinks and resistors. Please check the
capacitor surface temperature on the affected side.
Please install safety device in the cases where abnormal operations by failure of other components, or
when applying high voltage to the capacitors caused by kick voltage at switching.
(2) Handling
Sudden charge/discharge may cause characteristic degradation of capacitor. When charging or discharging,
pass through a resistance of 2kΩ or more.
Please be careful not to apply excessive force to the lead wire root area, which may cause crack or gap in
the coating resin near the root area.
(3) Storing and operating conditions
3-1.Storage product
Please keep the capacitor within temperature of 35℃ or less and humidity of 85%RH or less.
If capacitor was kept for long period, soldering property is fall by oxidation of lead wire surface.
Therefore we recommend the keeping period within 6month.
3-2. Humid environment
When used in high humidity for a long period, please check a performance and reliability beforehand,
because degradation of insulation resistance or oxidization of electrodes may occur due to the humidity
absorbed through the enclosure of the components.
3-3. Atmospheric gas
Hydrogen chloride, hydrogen sulfide, sulfurous acid etc., may lead to oxidization of electrodes and may
induce smoke emission and ignition.
3-4. Resin coat application
When using resin coating or resin embedding, please check a performance and reliability beforehand
because of following reason.
・The solvent contained in resin may attack the capacitors and characteristic degradation may be caused.
・Heat generated by the hardening resin may damage the capacitors.
・By expansive and contractile stress of resin to a capacitor, a lead-wire may be cut or a crack of solder
may occur.

Measuring method of a self-temperature rise
As shown in the following Fig.2, thermocouple is attached to the capacitor surface with adhesives,
andcapacitor surface temperature is measured under conditions not influenced by other components.
(Measurement is carried out at room temperature.)
If there are influences from other components, please measure with one of the following procedures.
a) Attach the capacitor on the other of PC board.
b) Mount the capacitor on the same PC board as the actual model and place them inside a box.
Connect to the main set and measure under no circulating air (refer to the following figure).
Same PC board as the actual model must be used to prevent the self-temperature rise variation caused
by the types of PC board, wiring pattern, etc.
Fig.2
T1 : Capacitor surface temperature – Must be measured at the capacitor center.
T2 : Atmosphere temperature
(Please use thermocouple φ0.1 typeT)
