6 FAQs about [Absorption capacitor]

What is dielectric absorption in capacitors?

How long does it take a capacitor to absorb a liquid?

The time it takes for a film capacitor to absorb liquid can vary, but typical values of the time constants for absorption/desorption range from half a day to several weeks. Long contact with humidity can produce irreversible effects.

What happens when moisture is absorbed by a capacitor?

The absorption of moisture increases the number of permanent dipoles inside the capacitor, producing reversible effects on capacitance, dissipation factor and insulation resistance, which are treated in the respective sections. Additional changes in the capacitor dimensions will follow as a consequence of film shrinkage.

What is the rated capacitance of a capacitor?

The rated capacitance CR of a capacitor is the value for which it is designed, and that is indicated on it. Capacitance is the amount of electrically charged carriers a capacitor can store per unit of voltage. Capacitance is measured under standard conditions to IEC 60068-1:2013.

How can capacitors be adapted to the desired capacitance value?

The capacitor's plate area can be adapted to the wanted capacitance value. The permittivity and the dielectric thickness are the determining parameter for capacitors. Ease of processing is also crucial. Thin, mechanically flexible sheets can be wrapped or stacked easily, yielding large designs with high capacitance values.

What happens when a capacitor is shorted?

If a capacitor is shorted, the voltage on the capacitor will slowly tend to recover to a fixed percentage of its original value. This percentage, typically between 0.01% and 10%, is a measure of dielectric absorption.
