Product specifications in this catalog are as of Dec. 2017, and are subject to change or
obsolescence without notice.
Please consult the approval sheet before ordering.Please read rating and Cautions first.

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.
When DC-rated capacitors are to be used in input circuits from commercial power source (AC filter),
be sure to use Safety Recognized Capacitors because various regulations on withstand voltage
or impulse withstand established for each equipment should be taken into considerations.

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 self-
generated heat due to dielectric-loss. The allowable frequency should be in less than 300kHz in sine
wave. 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
0.1mm
and be in the condition where capacitor is not affected by radiant heat of other components and
wind of surroundings. While, in case of non-sine wave which include a harmonic frequency, please
contact our sales representatives or product engineers.
3. 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.
4. VIBRATION AND IMPACT
Do not expose a capacitor or its leads to excessive shock or vibration during use.
5. 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
: 3.5 s max.

6. 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.
7. 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.
8. 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.
NOTE
1.Please make sure that your product has been evaluated in view of your specifications with our
product being mounted to your product.
2.You are requested not to use our product deviating from this specification.
