1-2 Technical Concepts
1-3 The Function of Electrolytic Capacitors
1. The material and structure of Electrolytic Capacitors
The electrolytic capacitors could be widely used in appliance (ie. TV , radio ,
Electrolytic Capacitor is a simple module . It simply contains an insulator
audio equipment , watching machine and air conditioner.......etc . ) , computer
between relative conductors in an electrode. The major internal raw material
equipment (mother board, image device & the peripherals such as the printer
contains an element constructed by an separator paper wrap around the
, drawing device, scanner etc) , communication equipment , estate equipment
anode foil and cathode foil , which is then impregnated with the electrolyte
, measure instrument and also the industrial instrument , air plane , firebomb ,
, inserted into an aluminum case and sealed.
satellite... etc. as a piloting equipment.
*According to the inflict electric wave & using purpose , it basically with some
classified purposes as below :
1. DC Voltage :
DC Voltage :
a. For Momentary High Voltage : For using to the impulse generator such as
the shock wave resistance test of the heavy electric machine .
b. For High Electric Current : For using to the welding machine , X - Ray
facility , copy machine and discharge processing device .
c. For DC High Voltage : The electrolytic capacitor and rectifier composing
, a special DC high voltage been happened after charged , for using to the
power of electronic microscope and accelerator .
d. For Integration & Memory : For either memory circuit or compare circuit
inside the calculator .
2. The DC voltage that with alternate ingredient :
a. For Wave Filter : Combination with the chip resistor & inductor as a internet
, to be past by DC current or some frequency to closure or decline some
other frequency .
b. For Bypass : A parallel track that outside from the circuit element , the IC

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 seal with rubber to stop the leakage of electrolyte
then slip into a sleeve to form the final product .
7. Aging : The purpose of Aging is to repair the oxide film damage by
recharging and electrolyte .
