Application Notes for Tantalum Solid Electrolytic Capacitor（Type 204）
1. Operating Voltage
Tantalum Solid Electrolytic Capacitor shall be operated at the rated voltage or lower.
Rated voltage: The “rated voltage” refers to the maximum DC voltage that is allowed to be continuously applied between the capacitor
terminals at the rated temperature.
Surge voltage: The “surge voltage” refers to the voltage that is allowed to be instantaneously applied to the capacitor at the rated
temperature or the maximum working temperature. The capacitor shall withstand the voltage when a 30-second cycle of application of
the voltage through a 1000 Ω series resistance is repeated 1000 times in 6-minute periods.
When designing the circuit, the equipment’s required reliability must be considered and appropriate voltage derating must be
performed. Figure 1 shows the recommended voltage derating curve for Tantalum capacitors as described by NASA APPLICATION
NOTES.
2. Application that contain AC Voltage
Special attention to the following 3 items.
(1) The sum of the DC bias voltage and the positive peak value of the AC voltage should not exceed the rated voltage.
(2) Reverse voltage should not exceed the allowable values of the negative peak AC voltage.
(3) Ripple current should not exceed the allowable values.
3. Reverse Voltage
Tantalum solid electrolytic capacitor is polarity. Please do not impress reverse voltage. As well, please confirm the potential of the tester
beforehand when both ends of the capacitor are checked with the tester etc.
4. Permissible Ripple Voltage
Permissible ripple voltage is determined by the heat loss of the element and heat radiation of the lead wire. This is influenced by
capacitance, ESR, operating temperature, and frequency or ripple. Please consult Matsuo’s Engineering Bulletin for details on
calculating ripple current values.
5. Application on low-impedance circuit
The failure rate of low impedance circuit at 0.1Ω/V is about five times greater than that of a 1Ω/V circuit. To curtail this higher failure
rate, tantalum capacitors used in low impedance circuits, such as filters for power supplies, particularly switching power supplies, or for
noise by-passing, require that operating voltage be derated to less than half of the rated voltage. Actually, less than 1/3 of the rated
voltage is recommended.
6. Non Polar Application(BACK TO BACK)
Tantalum capacitors can be used as a non-polar unit if two capacitors are connected “BACK-TO-BACK” when reserve voltage is
applied at a more than permissible value, or in a purely AC circuit. The two capacitors should both be of the same rated voltage and
capacitance tolerance, and they should both be twice the required capacitance value.
Ripple Voltage: Permissible Ripple Voltage shall not exceed the value allowed for either
C1 or C2 (This will be the same, as the capacitors should be identical.)
Capacitance: (C1 × C2) / (C1 + C2)
Leakage Current: If terminal A is (+), the Leakage Current will be equal to C1’s Leakage Current.
If terminal B is (+), the Leakage Current will be equal to C2’s Leakage Current.
7. Soldering
The soldering of Type 204 should be operated per the following recommended conditions.
(1) Flow Soldering
This type soldering is a way to solder parts from under the glass-epoxy PC board regarding which parts are put into hole of the board.
Figure 3 shows temperature and dipping time of solder Bath.
Regarding floor time, if it goes beyond the condition of Figure 3, in order to control temperature raise, spacer should be attached to lead
wire by Teflon, which can make products some raise from board. Figure 4 shows tolerance of temperature and dipping time on the
case.

(2) Soldering with a Soldering Iron
It is a soldering method that parts are heated up under board by soldering iron after putting parts into through-hole of PC board such as
item 7.11.Allowance is shown in Figure 5 regarding temperature and holding time of soldering iron.
8.Example of trouble phenomenon happening by excessive heating when soldering
When mounting, the following breakdown phenomena might be caused when excessive heating that exceeds the above-mentioned
tolerance is done. Therefore, please pay attention to the operation.
In a case that solder is used for cathode connection of molding type product, Ag in silver paste could merge into solder if solder in
product have melted. That might cause excessive Leakage Current and Short etc. by changing in deterioration in DF and the high
frequency impedance or internal stresses in that case.
Mechanical stress according to heat stress and expansion shrinkage or concentrations of internal stress might increase failure rate.
9.Flux
Please use flux as much as possible with non-acidity and little content of both chlorine and amine.
10. Cleaning
Cleaning by organic solvent may damage capacitor’s appearance and performance. However, our capacitors are not effected even
when soaked at 20 ~ 30°C 2-propanol for 5 minutes. When introducing new cleaning methods or changing the cleaning term, please
consult us.
11. Protective Resin Coating
After components are assembled to substrate, a protective resin coating is sometimes applied. As this resin coating cures, it gives
mechanical and thermal stress to Tantalum capacitors. This stress can cause damage to the capacitors, which affects their reliability.
Before using a resin coating, proper research must be done in regards to the material and process to insure that excessive stress will
not be applied to capacitors and other components.
12. Vibration
Approximately 300 G shall be applied to a capacitor, when dropped from 1 meter to a concrete floor.
Although capacitors are made to withstand this drop test, stress from shock due to falling or striking does cause damage to the
capacitors and increases failure rates. Do not subject capacitors to this type of mechanical stress.
13. Additional Notes
· When more than one capacitor is connected in series, a resistor that can distribute the voltage equally to the capacitors shall be
connected in parallel.
· The capacitor cases shall not be cut even if the mounting space is insufficient.
· During a customers aging process, voltage should remain under the rated voltage at all times.
· Capacitors should never be touched or manipulated while operating.
· Capacitors are not meant to be dismantled.
· When testing capacitors, please examine the power source before conducting test to insure the tester’s polarity and applied voltage.
· In the event of a capacitor burning, smoking, or emitting an offensive smell during operation, please turn the circuit “off” and keep
hands and face away from the burning capacitor.
· If a capacitor be electrical shorted, it becomes hot, and the capacitor element may ignite.
In this case, the printed board may be burnt out.
· Capacitors should be stored at room temperature under low humidity. Capacitors should never be stored under direct sunlight, and
should be stored in an environment containing dust.
· If the capacitors will be operated in a humid environment, they should be sealed with a compound under proper conditions.
· Capacitors should not be stored or operated in environments containing acids, alkalis or active gasses.
· When capacitors are disposed of as “scrap” or waste, they should be treated as Industrial Waste since they contain various metals
and polymers.
· Capacitors submitted as samples should not be used for production purposes.
These application notes are prepared based on “Guideline of notabilia for fixed tantalum electrolytic capacitors with solid electrolyte for
use in electronic equipment” (EIAJ RCR-2368) issued by Japan Electronics and Information Technology Industries Association (JEITA).
