Storage
Operating
1) The capacitors must be stored in an ambient temperature of 5 to 40℃
Condition
with a relative humidity of 20 to 70%RH. The products should be used
within 6 months upon receipt.
(Storage,
Transportation)
2) The capacitors must be operated and stored in an environment free of
dew condensation and these gases such as Hydrogen Sulphide, Hydrogen
Sulphate, Chlorine, Ammonia and sulfur.
3) Avoid storing in sun light and falling of dew.
4) Do not use capacitors under high humidity and high and low atmospheric
pressure which may affect capacitors reliability.
5) Capacitors should be tested for the solderability when they are stored for long
time.
1-2. Handling in transportation
In case of the transportation of the capacitors, the performance of the
capacitors
may be deteriorated depending on the transportation condition.
(Refer to JEITA RCR-2335C 9.2 Handling in transportation)
2-1. Operating temperature
Circuit design
Operating temperature should be followed strictly within this specification, especially
! Caution
be careful with maximum temperature.
1) Do not use capacitors above the maximum allowable operating temperature.
2) Surface temperature including self heating should be below maximum
operating temperature.
(Due to dielectric loss, capacitors will heat itself when AC is applied. Especially
at high frequencies around its SRF, the heat might be so extreme that it may
damage itself or the product mounted on. Please design the circuit so that the
maximum temperature of the capacitors including the self heating to be below
the maximum allowable operating temperature. Temperature rise at capacitor
surface shall be below 20℃)
3) The electrical characteristics of the capacitors will vary depending on the
temperature. The capacitors should be selected and designed in taking the
temperature into consideration.
2-2 Operating voltage
1) Operating voltage across the terminals should be below the rated voltage.
When AC and DC are super imposed, V0-P must be below the rated voltage.
——— (1) and (2)
AC or pulse with overshooting, VP-P must be below the rated voltage.
——— (3), (4) and (5)
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 the capacitors within rated voltage containing
these Irregular voltage.

2) Even below the rated voltage, if repetitive high frequency AC or pulse is applied,
the reliability of the capacitors may be reduced.
3) The effective capacitance will vary depending on applied DC and AC voltages.
The capacitors should be selected and designed in taking the voltages into
consideration.
2-3. Frequency
When the capacitors (Class 2) are used in AC and/or pulse voltages, the
capacitors may vibrate themselves and generate audible sound.

Designing
P.C. board
The amount of solder at the terminations has a direct effect on the reliability of the
capacitors.
1) The greater the amount of solder, the higher the stress on the chip capacitor, and
the more likely that it will break. When designing a P.C. board, determine the
shape and size of the solder lands to have proper amount of solder on the
terminations.
2) Avoid using common solder land for multiple terminations and provide individual
solder land for each terminations.
3) Size and recommended land dimensions.

5-1. Flux selection
Although highly-activated flux gives better solderability, substances which increase
activity may also degrade the insulation of the chip capacitors.
To avoid such degradation, it is recommended following.
1) It is recommended to use a mildly activated rosin flux (less than 0.1wt% chlorine).
Strong flux is not recommended.
2) Excessive flux must be avoided. Please provide proper amount of flux.
3) When water-soluble flux is used, enough washing is necessary.

Soldering
Condition
2) Direct contact of the soldering iron with ceramic dielectric of chip capacitors may
cause crack. Do not touch the ceramic dielectric and the terminations by solder
iron.
3) It is not recommended to reuse dismounted capacitors. (For soft electrode)
5-7.Soldering rework using spot heater
Heat stress during rework may possibly be reduced by using a spot heater
(also called a “blower”) rather than a soldering iron.
It is applied only to adding solder in the case of insufficient solder amount.
1) Reworking using a spot heater may suppress the occurrence of cracks in the
capacitor compared to using a soldering iron. A spot heater can heat up a capacitor
uniformly with a small heat gradient which leads to lower thermal
stress caused by quick heating and cooling or localized heating.
Moreover, where ultra-small capacitors are mounted close together on a printed circuit
board, reworking with a spot heater can eliminate the risk of direct contact between
the tip of a soldering iron and a capacitor.
2) Rework condition
If the blower nozzle of a spot heater is too close to a capacitor. a crack in the capacitor
may occur due to heat stress. Below are recommendations for avoiding such an
occurrence.
Keep more than 5mm between a capacitor and a spot heater nozzle.
The blower temperature of the spot theater shall be lower than 400℃.
The airflow shall be set as weak as possible.
The diameter of the nozzle is recommended to be 2mm(one-outlet type).The size is
standard and common.
Duration of blowing hot air is recommended to be 10s or less CGA3(CC0603),
CGA4(CC0805), CGA5(CC1206) and 30s or less for CGA6(CC1210),
CGA8(CC1812) and CGA9(CC2220), considering surface area of the capacitor and
melting temperature of solder.
The angle between the nozzle and the capacitor is recommended to be 45degrees in
order to work easily and to avoid partial area heating.
As is the case when using a soldering iron, preheating reduces thermal stress on
capacitors and improves operating efficiency.

Soldering
Condition
3) Amount of solder should be suitable to from a proper fillet shape.
Excess solder causes mechanical and thermal stress on a capacitor and
results in cracks. Insufficient solder causes weak adherence of the capacitor
to the substrate and may result in detachment of a capacitor and deteriorate
reliability of the printed wiring board.
See the example of appropriate solder fillet shape for 5-5.Amount of solder.
5-8. Sn-Zn solder
Sn-Zn solder affects product reliability.
Please contact TDK in advance when utilize Sn-Zn solder.
5-9. Countermeasure for tombstone
The misalignment between the mounted positions of the capacitors and the land
patterns should be minimized. The tombstone phenomenon may occur especially
the capacitors are mounted (in longitudinal direction) in the same direction of the
reflow soldering.
(Refer to JEITA RCR-2335C Annex A (Informative) Recommendations to prevent the
tombstone phenomenon)

Cleaning
1) If an unsuitable cleaning fluid is used, flux residue or some foreign articles may
stick to chip capacitors surface to deteriorate especially the insulation resistance.
2) If cleaning condition is not suitable, it may damage the chip capacitors.
2)-1. Insufficient washing
(1) Terminal electrodes may corrode by Halogen in the flux.
(2) Halogen in the flux may adhere on the surface of capacitors, and lower the
insulation resistance.
(3) Water soluble flux has higher tendency to have above mentioned problems (1)
and (2).
2)-2. Excessive washing
When ultrasonic cleaning is used, excessively high ultrasonic energy output
can affect the connection between the ceramic chip capacitor's body and the
terminal electrode. To avoid this, following is the recommended condition.
Power : 20W/ max.
Frequency : 40kHz max.
Washing time : 5 minutes max.
2)-3. If the cleaning fluid is contaminated, density of Halogen increases, and it may
bring the same result as insufficient cleaning.

2) Printed circuit board cropping should not be carried out by hand, but by using the
proper tooling. Printed circuit board cropping should be carried out using a board
cropping jig as shown in the following figure or a board cropping apparatus to
prevent inducing mechanical stress on the board.
(1)Example of a board cropping jig
Recommended example: The board should be pushed from the back side,
close to the cropping jig so that the board is not bent and the stress applied to
the capacitor is compressive.
Unrecommended example: If the pushing point is far from the cropping jig and
the pushing direction is from the front side of the board, large tensile stress is
applied to the capacitor, which may cause cracks.
