CAUTION
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 started to apply to the circuit or it is stopped applying, the irregular voltage may
be generated for a transit period because of resonance or switching. Be sure to use a capacitor
within rated voltage containing these irregular voltage.

2. OPERATING TEMPERATURE AND SELF-GENERATED HEAT
Keep the surface temperature of a capacitor below the upper limit of its rated operating temperature
range. Be sure to take into account the heat generated by the capacitor itself.
When the capacitor is used in a high-frequency current, pulse current or the like, it may have the selfgenerated heat due to dielectric-loss. Applied voltage should be the load such as self-generated
heat is within 20 °C on the condition of atmosphere temperature 25 °C. When measuring, use a
thermocouple of small thermal capacity-K of φ0.1mm and be in the condition where capacitor is not
affected by radiant heat of other components and wind of surroundings. Excessive heat may lead to
deterioration of the capacitor’s characteristics and reliability.(Never attempt to perform measurement
with the cooling fan running. Otherwise, accurate measurement cannot be ensured.)
3. TEST CONDITION FOR WITHSTANDING VOLTAGE
(1) TEST EQUIPMENT
Test equipment for AC withstanding voltage should be used with the performance of the wave similar
to 50/60 Hz sine wave.
If the distorted sine wave or over load exceeding the specified voltage value is applied, the defective
may be caused.
(2) VOLTAGE APPLIED METHOD
When the withstanding voltage is applied, capacitor’s lead or terminal should be firmly connected
to the out-put of the withstanding voltage test equipment, and then the voltage should be raised
from near zero to the test voltage.
If the test voltage without the raise from near zero voltage would be applied directly to capacitor, test
voltage 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 capacitor’s lead or terminal should be taken off the out-put of the
withstanding voltage test equipment.
If the test voltage without the raise from near zero voltage would
voltage sine wave
be applied directly to capacitor, the surge voltage may arise,
and therefore, the defective may be caused.
0V
*ZERO CROSS is the point where voltage sine wave pass 0V.

- See the right figure 4. FAIL-SAFE
When capacitor would be broken, failure may result in a short circuit. Be sure to provide an
appropriate fail-safe function like a fuse on your product if failure would follow an electric shock,
fire or fume.
5. VIBRATION AND IMPACT
Do not expose a capacitor or its leads to excessive shock or vibration during use.

6. SOLDERING
When soldering this product to a PCB/PWB, do not exceed the solder heat resistance specification of
the capacitor. Subjecting this product to excessive heating could melt the internal junction solder and
may result in thermal shocks that can crack the ceramic element.
When soldering capacitor with a soldering iron, it should be performed in following conditions.
Temperature of iron-tip : 400 °C max.
Soldering iron wattage : 50W max.
Soldering time
: 3.5s max.
7. BONDING, RESIN MOLDING AND COATING
In case of bonding, molding or coating this product, verify that these processes do not affect the
quality of capacitor by testing the performance of the bonded, molded or coated product in the
intended equipment.
In case of the amount of applications, dryness / hardening conditions of adhesives and molding
resins containing organic solvents (ethyl acetate, methyl ethyl ketone, toluene, etc.) are unsuitable,
the outer coating resin of a capacitor is damaged by the organic solvents and it may result, worst
case, in a short circuit.
The variation in thickness of adhesive, molding resin or coating may cause a outer coating resin
cracking and/or ceramic element cracking of a capacitor in a temperature cycling.
8. TREATMENT AFTER BONDING, RESIN MOLDING AND COATING
When the outer coating is hot (over 100 ℃) after soldering, it becomes soft and fragile.
So please be careful not to give it mechanical stress.
Failure to follow the above cautions may result, worst case, in a short circuit and cause fuming or
partial dispersion when the product is used.
9. OPERATING AND STORAGE ENVIRONMENT
The insulating coating of capacitors does not form a perfect seal; therefore, do not use or store
capacitors in a corrosive atmosphere, especially where chloride gas, sulfide gas, acid, alkali, salt or
the like are present. And avoid exposure to moisture. Before cleaning, bonding, or molding
this product, verify that these processes do not affect product quality by testing the performance of a
cleaned, bonded or molded product in the intended equipment. Store the capacitors where the
temperature and relative humidity do not exceed -10 to 40 °C and 15 to 85%.
Use capacitors within 6 months after delivered. Check the solderability after 6 months or more.

NOTICE
1. CLEANING (ULTRASONIC CLEANING)
To perform ultrasonic cleaning, observe the following conditions.
Rinse bath capacity : Output of 20 watts per liter or less.
Rinsing time : 5 min maximum.
Do not vibrate the PCB/PWB directly.
Excessive ultrasonic cleaning may lead to fatigue destruction of the lead wires.
2. CAPACITANCE CHANGE OF CAPACITORS
⋅ Class 1 capacitors
Capacitance might change a little depending on a surrounding temperature or an applied voltage.
Please contact us if you use for the strict time constant circuit.
⋅ Class 2 and 3 capacitors
Class 2 and 3 capacitors like temperature characteristic B, E and F have an aging characteristic,
whereby the capacitor continually decreases its capacitance slightly if the capacitor leaves for a long
time. Moreover, capacitance might change greatly depending on a surrounding temperature or an
applied voltage. So, it is not likely to be able to use for the time constant circuit.
Please contact us if you need a detail information.
3. PERFORMANCE CHECK BY EQUIPMENT
Before using a capacitor, check that there is no problem in the equipment's performance and the
specifications.
Generally speaking, CLASS 2 ceramic capacitors have voltage dependence characteristics and
temperature dependence characteristics in capacitance. So, the capacitance value may change
depending on the operating condition in a equipment. Therefore, be sure to confirm the apparatus
performance of receiving influence in a capacitance value change of a capacitor, such as leakage
current and noise suppression characteristic.
Moreover, check the surge-proof ability of a capacitor in the equipment, if needed, because the surge
voltage may exceed specific value by the inductance of the circuit.
NOTE
1.Please make sure that your product has been evaluated in view of your specifications with our
product being mounted to your product.

Test method
Fix the body of capacitor, a tensile weight
gradually to each lead wire in the radial direction of
capacitor up to 10N and keep it for 10±1 s.
With the termination in its normal position, the
capacitor is held by its body in such a manner that
the axis of the termination is vertical; a mass
applying a force of 5N is then suspended from the
end of the termination.
The body of the capacitor is then inclined,
within a period of 2 to 3 s, through an angle of
approximately 90° in the vertical plane and then
returned to its initial position over the same period
of time; this operation constitutes one bend.
One bend immediately followed by a second bend
in the opposite direction.
The capacitor should be firmly soldered to the
supporting lead wire and vibration which is 10 to
55Hz in the vibration frequency range,1.5mm in
total amplitude, and about 1min in the rate of
vibration change from 10Hz to 55Hz and back to
10Hz is applied for a total of 6 h; 2 h each in
3 mutually perpendicular directions.
The lead wire of a capacitor should be dipped into a
ethanol solution of 25wt% rosin and then into
molten solder for 2±0.5 s. In both cases the depth of
dipping is up to about 1.5 to 2.0mm from the root of
lead wires.
