nanohenrys

A nanohenry is a unit of electrical inductance equal to one billionth of a henry. The henry, symbolized by the letter H, is the standard unit of inductance in the International System of Units (SI). Inductance is a property of an electrical conductor that opposes changes in the electric current flowing through it. This opposition arises from the magnetic field produced by the current. When the current changes, the magnetic field also changes, inducing a voltage that opposes the original change in current. The amount of inductance determines how much voltage is induced for a given rate of change in current.

The prefix "nano" signifies a factor of 10^-9. Therefore, one nanohenry (nH) is equivalent to 1 x 10^-9 henrys. This is a very small unit of inductance, commonly encountered in electronic circuits dealing with high frequencies or very small components, such as in radio frequency (RF) circuits, microelectronics, and integrated circuits. For context, a typical inductor found in power supply filtering might have inductance in the millihenry (mH) or even henry range, while inductors used for tuning resonant circuits in communication devices might be measured in nanohenrys or even picohenrys. The precise value of inductance is crucial for the performance and functionality of many electronic devices, affecting characteristics like resonance frequency, impedance, and signal filtering.
