farad (făr`əd) [for Michael Faraday Faraday, Michael (fâr`ədē, –dā'), 1791–1867, English scientist. ..... Click the link for more information. ], unit of electrical capacitance capacitance, in electricity, capability of a body, system, circuit, or device for storing electric charge. Capacitance is expressed as the ratio of stored charge in coulombs to the impressed potential difference in volts. .....

One Farad (F) is equal to an increase of one volt when a charge of one coulomb is applied. In microelectronics, measurements are typically in microFarads (mF) or picoFarads (pF). See capacitance and coulomb. farad Physics the derived SI unit of electric capacitance; the capacitance of a capacitor between the plates of which a potential of 1 volt is created by a charge of 1 coulomb. farad [′fa‚rad] (electricity) The unit of capacitance in the meter-kilogram-second system, equal to the capacitance of a capacitor which has a potential difference of 1 volt between its plates when the charge on one of its plates is 1 coulomb, there being an equal and opposite charge on the other plate.

This reduces the size of the required output capacitor from 470 microfarads to 47 microfarads, and the output inductor from 220 microhenry to 47 microhenry. Traditional termination techniques require large stabilization capacitors of up to 100 microfarads in value and size, along with smaller, high-frequency capacitors. |
