ALUMINUM ELECTROLYTIC TECHNICAL NOTE 1 General …

101 NOTED esign, Specifications are subject to change without factory for TECHNICAL specifications before purchase and/or ELECTROLYTICCAPACITORSTECHNICAL ( )1 General Description of ALUMINUM Elec-trolytic Capacitors 1-1 The Principle of CapacitorThe principle of capacitor can be presented by theprinciple drawing as in a voltage is applied between the metal elec-trodes placed opposite on both surfaces of a dielec-tric, electric charge can be stored proportional to VQ : Quantity of electricity (C)V : Voltage (V)C : Capacitance (F) C. called the capacitance of capacitor, is expressed bythe following expression with the electrode area S[m2],the electrode spacing t [m] and the dielectric constantof dielectric :C[F] = 0 0: Dielectric constant in vacuum ( = 12F/m ) The dielectric constant of an ALUMINUM oxide film is7 to 8. Larger capacitances can be obtained by en-larging the electrode area S or reducing t.
