WebPerformance comparison of power inductors The primary factors for comparing power inductor performance are the 1) inductance value, 2) DC superposition characteristic, 3) … Webpermeability inductor. The inductance starts falling off as current rises. Conversely, a high permeability switched mode power supply (SMPS) inductor holds the inductance as current increases and eventually drops off at saturation. A SMPS needs the inductance to be stable to provide regulation and stability of the system.

An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil. When the current flowing through the coil changes, the time-varying … Zobraziť viac An electric current flowing through a conductor generates a magnetic field surrounding it.
