Unit fF
Name femtofarad
Category Capacitance
Details A femtofarad (fF) is a unit of capacitance in the field of electronics and electrical engineering. It is a subdivision of the farad, the SI (International System of Units) unit of capacitance. A femtofarad represents 10^-15 farads, or one quadrillionth (1/1,000,000,000,000,000) of a farad.

Capacitance is a measure of an electronic component's ability to store and release electrical energy, typically in capacitors. Capacitors are passive electrical components used in electronic circuits for various purposes, such as filtering, signal coupling, decoupling, voltage regulation, energy storage, and frequency tuning.

A femtofarad range of capacitance is extremely small and can be found in ultra-high-frequency applications and integrated circuits, among other advanced technologies where extremely low levels of capacitance are required.
