Definition

Noun: A unit of electrical capacitance equal to one thousandth (10⁻³) of a farad. It is a metric subunit used to measure the ability of a component to store an electric charge.

Usage

The term "millifarad" is used in electrical engineering and electronics to specify capacitance values that are more conveniently expressed than using very small decimal fractions of a farad. It is a precise technical term.

Examples
  • The capacitor in the circuit has a value of 47 millifarads.
  • Older electrolytic capacitors were often rated in millifarads, whereas modern ones are more commonly rated in microfarads.
  • To convert from farads to millifarads, you multiply the value by 1,000 (e.g., 0.022 F = 22 mF).
Advanced Usage
  • The millifarad is part of a standardized metric prefix system for units. While common in some technical contexts, the microfarad (µF, 10⁻⁶ F) and picofarad (pF, 10⁻¹² F) are more frequently encountered in modern electronics documentation than the millifarad.
Variants and Related Words
  • Farad (F): The SI base unit of electrical capacitance.
  • Microfarad (µF): A unit equal to one millionth (10⁻⁶) of a farad.
  • Nanofarad (nF): A unit equal to one billionth (10⁻⁹) of a farad.
  • Picofarad (pF): A unit equal to one trillionth (10⁻¹²) of a farad.
  • Capacitance: The property measured by these units.
Synonyms
  • mF (the standard abbreviation).
  • There are no true conceptual synonyms, as it is a specific unit of measurement.
Related Phrases / Abbreviations
  • mF: The standard written abbreviation for millifarad. It is crucial not to confuse this with "MF," which is an old, non-standard abbreviation for microfarad. The correct abbreviation for microfarad is µF.
