Unit Information
Nanofarad
A metric subunit of electrical capacitance equal to one billionth of a farad (10⁻⁹ F). Commonly used for small-value capacitors in high-frequency circuits, RF applications, and precision timing circuits. Represents typical capacitance values for ceramic capacitors, mica capacitors, and other components used in oscillators, filters, and resonant circuits. Essential for high-frequency applications, impedance matching networks, and noise filtering where precise capacitance values are critical for circuit performance and signal integrity.
Picofarad
A metric subunit of electrical capacitance equal to one trillionth of a farad (10⁻¹² F). Widely used for very small capacitance values in high-frequency circuits, RF systems, and precision applications. Common for ceramic disc capacitors, variable capacitors, and trimmer capacitors used in tuning circuits, antenna matching, and high-frequency filters. Critical for RF design, microwave circuits, and high-speed digital applications where parasitic capacitance affects performance. Essential for characterizing stray capacitance and designing high-frequency systems.

Scientific Overview
Capacitance is the ability of a system to store electrical energy in an electric field. It is measured in farads (F) and represents the ratio of electric charge to electric potential difference.
Historical Background
The concept of capacitance was developed in the 18th century with the invention of the Leyden jar. Michael Faraday conducted pioneering research on capacitance, and the unit farad is named after him.
Real-World Applications
