What is Microhenry (µH) and How is it Used in Electrical Circuits?

Microhenry (μH) is a unit of measurement for the inductance of an electrical circuit or component. It is defined as one millionth of a henry (H), which is the unit of inductance.

In other words, if something has an inductance of 1 henry, then it has an inductance of 1,000,000 microhenries (1 H = 1,000,000 μH).

Microhenries are commonly used to measure the inductance of small components such as inductors and transformers, as well as in high-frequency applications where the inductance of a component can change rapidly with frequency.

For example, a typical air core inductor might have an inductance of around 100 μH at 100 MHz, while a surface mount inductor might have an inductance of around 1 μH at the same frequency.
