Handling precautions for High voltage ceramic capacitors
Please read the following closely before using these products.
Safety precautions
The following precautions should be observed strictly to ensure safety design.
Misuse of the product may lead to smoking of the product.
！
Cautions
1.Operating voltage
Use within the rated voltage of capacitor between terminals. For DC rated voltage application,
you should control the peak voltage (Vo-p) under the rated voltage in case the AC voltage is
superimposed on the DC voltage. Use within the rated voltage includes peak voltage (Vp-p) when
AC voltage or impulse voltage applied in a circuit. Confirm irregular voltage (surge voltage, static
electricity, switching noise, etc) occurs in the equipment used, and use within the rated voltage
containing the irregular voltage.
When the capacitor is used as a noise suppressor in the AC primary circuit, the voltage proof test
should be within the specified conditions (voltage, time, wave form, etc).
Connect by confirmation of non lose contact, and the voltage is started to apply to the circuit from
zero to the specified voltage and it is stopped applying from the voltage to zero.

2. Operating temperature
Be sure to use only those operating temperature described in our catalogue or specification.
Keep the surface temperature under the maximum temperature, which includes the maximum
self-heat temperature of 20 degree C.
3. Self-exothermal
Self-exothermal temperature should be within 20 degree C on the condition of atmosphere
temperature 25 degree C without the influence of wind such as the cooling fan. Be sure to use a
capacitor in a circuit of current increase by AC voltage or pulse voltage applied.
When high frequency voltage or impulse voltage applied in a circuit, reliability should be influenced.
Take into considerations the load reduction and self-exothermal temperature, even if voltage should
be within the rated voltage.

Cautions
4. Capacitance change of capacitors
For some of the capacitors, capacitance value may change considerably in the temperature range, or
by applied DC voltage. And capacitor has aging characteristic (capacitance decreases by keeping as it is).
When you use the capacitor in the time constant circuit, consult TDK whether the capacitor is available or
not.
5. Vibration of capacitors
When the capacitor class 2 is used in the AC circuit, or pulse circuit, the capacitor might vibrate or noise
might occur in the specified frequency. Be sure to confirm the conditions before using the capacitor.
6. Usage of capacitance and storage
Don’t use capacitors in the following environments:
* Direct sunshine
* Areas directly exposed to water or salty water
* Areas that become dewy
* Areas filled with toxic gases (such as hydrogen sulfide, sulfur dioxide, chlorine, ammonia, etc)
* Areas exposed to excess vibrations or shock conditions described in our catalogue or specification.
Store capacitors in an environment from -10 to 40 degree C, with 15 to 70%RH for 6 months maximum
and use within the period after receiving the capacitors.
7. Inserting precautions
When inserting capacitors into the PC board by automatic insertion machine, confirm the conditions
(such as pressure of pusher, adjustment of clinching portion) and minimize the impact force by
chucking the body, or clinching the lead terminals.
Distances between the hole position onto a PC board should be equal to the pitch of capacitors.
When stretching the lead terminal, any force may load the bottom of the capacitor body and result in
damage to the insulation coating. Severe damages may cause poor reliability.
8. Soldering
Don’t immerse the capacitor body into the molten solder, and don’t solder the terminals by reflow
soldering. Use PC board, and solder the terminals in the opposite side of the body. Soldering conditions,
such as pre-heat temperature, soldering temperature, and soldering time, should be followed by the
descriptions in our catalogue or specification. (refer to Fig.-1)
Adjust the amount of solder within the proper volume. Select an appropriate soldering material.
When using soldering iron for installing capacitors or reworking onto the PC board, sufficient pre-heating
and temperature control should be used. We recommend that the iron condition is 350±10 degree C/
3.5±0.5s. as 1 time, and you should use an adequate tip diameter (φ3mm Max.) with the soldering iron as
w
ell as a proper wattage (50W Max.). Don’t touch the capacitor body directly with soldering tip,
except for the terminals of capacitor.
9. Flux
When using flux for soldering capacitors onto the PC board, spread it thinly and uniformly.
Flux will be composed of halogenated material less than 0.1 wt% (cl conversion).
Don’t use a strong acid grade of flux. When using water-soluble flux, sufficient cleansing should
be done.

Cautions
10. Cleansing
When the cleansing should not be sufficient, the cleansing liquid or any residue might leave on the
capacitor body, they may deteriorate the insulation coating or performance (insulation resistance, etc.).
When using ultrasonic cleansing, avoid transmitting vibrations onto the PC board. Conditions of
ultrasonic cleansing, such as output frequency and time of the method, should be taken into
considerations.
After cleansing capacitors, dry them well. Cleansing liquid should not contain electrolyte, nor leave
any residue. Through the result of the cleansing method, confirm whether the quality of the capacitors
have been affected due to the conditions.
11. Coating or molding
When coating or molding capacitors after installing components onto the PC board, confirm whether
the performance of capacitors may not be damaged by the work.
12. Mechanical stress
Don’t submit to excessive mechanical shock. Don’t use capacitors which may have been damaged due
to dropping, etc.
If possible, avoid bending the terminals of capacitors. In an unavoidable case of bending, use a small
jig to decrease the mechanical stress on the capacitors.
13. Others
Please contact TDK before using our capacitors listed in this catalogue or specifications for the
applications listed below which require especially high reliability for the prevention of defects
which might directly cause damage to the third party’s life, body or property, or when intending to use
one of our capacitors for other applications than specified in this catalog or specifications.
* Medical equipment
* Aerospace equipment
* Power plant equipment
* Aircraft equipment
* Transportation equipment (vehicles, trains, ships, etc)
* Undersea equipment
* Traffic signal equipment
* Disaster prevention, crime prevention equipment
* Data processing equipment exerting influence on public
* Application of similar complexity and, or reliability requirements to the applications listed in
the above.
Please refer to the guideline of notabilia for fixed ceramic capacitors issued by JEITA (Japan Electronics
and Information Technology Association, EIAJ RCR-2335).
