A henry is the SI unit of inductance. One henry induces one volt when the current changes at one ampere per second.
Inductor values commonly range from nanohenries (nH) in RF circuits to millihenries (mH) in power supplies.
Multiply henries by 1000 to get millihenries. For example, 0.01 H = 10 mH.
1 millihenry (mH) = 1000 microhenries (µH). This is the most common range for power supply inductors.
Inductors are used in power supplies (energy storage), filters (blocking AC while passing DC), transformers, and RF circuits (tuning and impedance matching).
Multiply millihenries by 1000 to get microhenries. For example, 4.7 mH = 4700 µH.
Inductors store energy in a magnetic field and resist changes in current. Capacitors store energy in an electric field and resist changes in voltage.
