Type TCA is a tantalum solid electrolytic capacitor which uses conductive polymer as cathode layer.
Their equivalent series resistance (ESR) is extremely lowered with the characteristics of the polymer having high electric conductivity.
This ensures higher permissible ripple current and excellent noise absorption performance on high-frequency circuits.
Mobile phones, digital cameras, high-performance portable equipments, personal computers, digital TV sets, DC/DC converters, regulators
and peripherals.
1. Low ESR and Low impedance
Using a conductive polymer as cathode layer makes low ESR and impedance possible.
Type TCA makes high permissible ripple current and is suitable for noise bypass application.
2. Stable ESR over temperature
ESR is extremely stable from low temperature through high temperature.
3. Compact and Large capacitance
The capacitor is smaller and has larger capacitance than ceramic capacitor and aluminum electrolytic capacitor.
4. Benign Failure Mode
Type TCA offers very safe characteristics which makes ignition and smoking harder by taking advantages of characteristics of conductive
polymer if the capacitor be short-circuited.
5. Lead Free and RoHS Compliant.

Application Notes for Tantalum Solid Electrolytic Capacitor with Conductive Polymer
1. Operating voltage
The capacitors shall be operated at the rated voltage or lower. Over rated voltage
applied even for a short time may cause short failure.
When designing the circuit, the equipment‟s required reliability must be considered
and appropriate voltage derating must be performed.
· Recommended operating voltage : 80% or less of the rated voltage
· When the operating temperature exceeds 85, derate the applied voltage.
The voltage derating formula is shown below.
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 voltage should not exceed the allowable values.
3. Reverse voltage
Special attention to the polar character.
Reverse Voltage should not be applied.
4. Permissible ripple current
The permissible ripple current and voltage at about 100 kHz or higher can be
determined by the following formula from the permissible power loss for each case
size (Pmax value) shown in Table 1 and the specified ESR value. However, when the
expected operating temperature is higher than room temperature, determine the
permissible values multiplying the Pmax value by the specified multiplier (Table 2).
For the permissible values at different frequencies, consult our Sales Department.

ESR: Specified ESR value at regulated frequency (Ω)
Z : Impedance at regulated frequency (Ω)
Table 1 Permissible power loss for each case size
Note: Above values are measured at 0.8t glass epoxy board mounting in free air and
may be changed depending on the kind of board, packing density, and air
convection condition. Please consult us if calculated power loss value is
different from above list of P max value.
Table 2 Pmax multiplier at each operating temperature
5. Non Polar Connection
The capacitor cannot be used as a non-polar unit.
6. Soldering
6.1 Preheating
To obtain optimal reliability, lowering the heat shock during the soldering process is
favorable. Capacitors should be pre-heated at 130-160 for approximately 60
seconds.
6.2 Soldering
The body of the capacitor should not exceed 240 during soldering.
(1) Reflow Soldering
Reflow soldering is a process in which the capacitors are mounted on a printed
circuit board with solder paste. Two methods of Reflow Soldering: Direct and
Atmospheric Heat.
· Direct Heat (Hot plate)
· Atmospheric Heat
a) Near and Far IR Ray
b) Convection Oven
Vapor Phase Soldering and Flow Soldering are not recommended.
(2) Soldering Iron
Soldering with a soldering iron cannot be recommended due to the lack of
consistency in maintaining temperatures and process times. If this method
should be necessary, the iron should never touch the capacitor‟s terminals, and
the temperature of the soldering iron should never exceed 350. The
application of the iron should not exceed 3 seconds and 30 watt.
(3) Please consult us for other methods.
7. Solvent cleaning
Cleaning by organic solvent may damage capacitor‟s appearance and performance.
However, our capacitors are not effected even when soaked at 20-30 2-propanol
for 5 minutes. When introducing new cleaning methods or changing the cleaning term,
please consult us.
8. Ultrasonic cleaning
Ultrasonic cleaning under severe condition may break terminals. Also, from an
electrical characteristics aspect, it is unfavorable. Therefore, please do not use
ultrasonic cleaning if possible. If the Ultrasonic cleaning process will be used, please
note the following.
(1) The solvent should not be boiled. (Lower the ultrasonic wave output or use
solvent with the high boiling point.)
(2) The recommended wattage is less than 0.5 watts per cm2.
(3) The cleaning time should be kept to a minimum. Also, samples must be swang
in the solvent. Please consult us.
9. Storage
Capacitors should be tightly sealed in moisture prevention bag and stored with
supplied reel.
10. Inapplicable circuits
The capacitors may cause nonconformity if they are used on the following circuits.
(1) High-impedance voltage holding circuits
(2) Coupling circuits
(3) Time constant circuits
(4) Circuits significantly affected by leakage current
If a short circuit occurs, the capacitors may generate heat or smoke depending on the
short-circuit current.
When designing a circuit, take the instructions stated herein into consideration, and
take as much redundant measures as possible.
These application notes are prepared based on the technical report RCR-2368B
"Guideline of notabilia for fixed tantalum electrolytic capacitors with solid electrolyte for
use in electronic equipment" issued by Japan Electronics and Information Technology
Industries Association. For the details of the instructions (explanation, reasons and
concrete examples), please refer to this guideline, or consult our Sales Department.
