RECOMMENDED PAD DIMENSIONS
Type ACA is an aluminum solid electrolytic capacitor which uses conductive polymer as cathode layer. In order to meet
customer needs of digitization and higher frequency of electronics device, we have developed conductive polymer aluminum
solid electrolytic capacitor with ULTRA Low ESR, which is excellent in electrically conductive and high-temperature stability.
Computer, computer peripherals, mother board, DC/DC converter and, regulator peripherals.
１．Low ESR and Low impedance
Using conductive polymer as cathode layer makes lower ESR and impedance possible, especially at high-frequency
range.
２．Temperature Stability
ESR and capacitance are stable from low temperature through high temperature.
３．Category temperature range is -55°C to +105°C. No derating with temperature is required.
４．Failure mode
ACA offers very safe characteristics which makes ignition and smorking harder by taking advantages of characteristics of
materials if the capacitor be short-circuited.
５．Lead free and RoHS compliant.
In order to expect the self alignment effect, it is recommended that land width is almost the same size as terminal of capacitor,
and space between lands(c) nearly equal to the space between terminals for appropriate soldering.

■ Application Notes for Conductive Polymer Aluminum Solid Electrolytic Capacitor
1. Operating Voltage
Aluminum Capacitor 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.
2. Application that contains 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 (refer page3)
(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
Permissible ripple current and voltage is determined by the following formula and
influenced by P max value and ESR standard value. Please consult us in case of
different frequency.

Note: Above values are measured at 0.6t ceramic board-mounting and 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.
5. Leakage current
Leakage current can be increased by heat and mechanical stress of soldering.
Turning on electricity decreases leakage current.
6. Non Polar Connection
Aluminum Solid Electrolytic Capacitor cannot be used as a non-polar unit.
7. Soldering
7.1. Pre-heating
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.
7.2. 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
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.
8. 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.
9. 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.
10. Storage
Capacitors should be tightly sealed in moisture prevention bag and stored with
supplied reel.
