where resistance in ohms and capacitance in farads yields the time constant in seconds or the cutoff frequency in hertz (Hz). The cutoff frequency when expressed as an angular frequency ( ω c = 2 π f c ) {\displaystyle (\omega _{c}{=}2\pi f_{c})} is simply the reciprocal of the time constant.
Capacitance is the ability of an object to store electric charge. It is measured by the change in charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance.
The large capacitance per unit volume of electrolytic capacitors make them valuable in relatively high-current and low-frequency electrical circuits, e.g. in power supply filters for decoupling unwanted AC components from DC power connections or as coupling capacitors in audio amplifiers, for passing or bypassing low-frequency signals and ...
The farad (symbol: F) is the unit of electrical capacitance, the ability of a body to store an electrical charge, in the International System of Units (SI), equivalent to 1 coulomb per volt (C/V). [1] It is named after the English physicist Michael Faraday (1791–1867). In SI base units 1 F = 1 kg −1 ⋅m −2 ⋅s 4 ⋅A 2.

The capacitance frequency dependence of polyester film capacitors compared with the other film capacitors is -3% in the range from 100 Hz to 100 kHz at the upper limit. Also, the temperature and frequency dependence of the dissipation factor are higher for polyester film capacitors compared with the other film capacitor types.
The capacitance value specified in the data sheets of the manufacturers is called the rated capacitance C R or nominal capacitance C N and is the value for which the capacitor has been designed. The standardized measuring condition for electrolytic capacitors is an AC measuring method with 0.5 V at a frequency of 100/120 Hz at a temperature of ...
The capacitance value specified in manufacturers' data sheets is called the rated capacitance C R or nominal capacitance C N and is the value for which the capacitor has been designed. Standardized measuring conditions for electrolytic capacitors are an AC measurement with 0.5 V [ clarification needed ] at a frequency of 100/120 Hz and a ...
