Electrolytic Capacitor is a simple module. It simply contains an insulator between relative conductors in an electrode.
The major internal raw material contains an element constructed by an separator paper wrap around the anode foil and cathode foil, which is then impregnated with the electrolyte, inserted into an aluminum case and sealed.

Production Processes

1. Etching: The process to increase surface area of aluminum foil by using chemical erosion or chemical corrosion method is called Etching. Normally chemical corrosion method uses the ripple current of electrolyte, combination of the liquid and temperature to determine the size, shape, and quantity of the dense network of microscopic channels on the aluminum foil surface.

2. Forming: The production process of the anode aluminum foil of electrolytic capacitors is by anodic oxidation of the etched aluminum foil. The production of the cathode aluminum foil sometimes involves oxidation in special purposes. This anodic oxidation process is called

Forming. Boric acid or organic acid is used for high voltage forming and phosphoric acid or ammonium adipose is used for low voltage forming in order to obtain stable natural oxide layer of Al2O3.

3. Slitting: The cutting of the aluminum foil and separator paper according to the required length.

4. Winding: The stitching or cold welding of cut anode and cathode foils and tab terminal, and wrap the electrolytic paper in between the anode and cathode, then fix the end with glue or sticky tape, and attached leads is called the capacitor "element".

5. Impregnation: The process of eliminating the water from the elements by pressurizes or vacuum in order to soak the element with the electrolyte is called Impregnation. The elements fully filled with electrolyte is then centrifuged to remove excess electrolyte.

6. Assembly: The elements are sealed with rubber to stop the leakage of electrolyte then put into a sleeve to form the final product.

7. Aging: The purpose of aging is to repair the oxide layer damage by recharging and electrolyte.

The electrolytic capacitors could be widely used in appliance (ie. TV, radio, audio equipment, washing machine and air conditioner…etc.), computer equipment (motherboard, image device & the peripherals such as the printer, drawing device, scanner... etc.), communication equipment, estate equipment, measuring instrument and also the industrial instrument, air plane, firebomb, satellite…etc. as a piloting equipment.
