Color ring inductors, similar to common color ring resistors, usually use three or four color rings to mark the inductance quantity.
Magnetic beads are specially designed to suppress high-frequency noise and spike interference on signal lines and power lines, and also have the ability to absorb electrostatic pulses. Magnetic beads are used to absorb UHF signals.
Inductance may be made by winding a core of conductive material, typically copper wire, or the core may be removed or replaced with a ferromagnetic material. Core materials with higher permeability than air can bind the magnetic field more tightly around the inductance element, thus increasing the inductance.
The Inductor is a device that stores electrical energy as magnetic energy. The structure of an inductor is similar to that of a transformer, but with only one winding. An inductor has a certain inductance that only resists changes in current.
Inductance is the ratio of the magnetic flux in a wire to the current producing the alternating flux around the inside of the wire when an alternating current is flowing through it.
Patch inductance and current convert electrical energy, store it, and then release it, which is why capacitors discharge.
