The absorption capacitance was calculated as a ratio of the charge, Qt, that is transferred into the dielectric during polarization and applied voltage, Ct = Qt/V. The value of Qt was calculated by integrating of the absorption current with time of polarization.
The released charges are manifested as a residual voltage in the capacitor and is measured in V. This residual voltage is a measure on the dielectric absorption ”DA” of the capacitor and is expressed in percent of the initial voltage applied. Figure C1-9. Effect of dielectric absorption.
In several cases that were related to high volumetric efficiency capacitors, no decrease in the resistance after damage was due to the capacitor’s initial low resistance. In these cases, the intrinsic leakage current exceeded the damage-related currents, thus masking the presence of the defects.
In most cases, the maximum Vabs exceeded 1 or 2 volts, and the capacitor might remain at voltages above 1 V even after hundreds of hours of storage in room conditions.
International standards speak of the Dielectric Constant or permittivity, designated by the symbol ε. A capacitor serves as a reservoir for electric charges. The size of the ”reservoir” is called capacitance and is expressed in the quantity F (arad) or As/V.
According to the model, absorption voltage depends on the ratio of Ct/C0, rather than on the nominal value of capacitance. Considering that the ratio Ct/C0 remains within a rather narrow range, from 10% to 50%, variations of the maximum value of Vabs for different part types is also relatively small.
