The production of an integrated inductor is determined by the choice of magnetic core. The following is an explanation of the manganese zinc magnetic core of the inductor and its advantages in use:
Manganese zinc magnetic core is a type of soft magnetic core with high initial permeability. The surface resistance of this product is low, and the higher the initial permeability, the lower the surface resistance. Therefore, it is generally used in circuits below 1MHz.
Main use: The initial permeability of this material is generally around 2000-3000, with a high saturation magnetic flux density and low losses. It is one of the most ideal power inductor cores at around 100KHz.
Nickel zinc iron core is a type of soft magnetic ferrite core, with an initial permeability of 5-1500. Due to its high surface resistance, this core is generally used in medium to high frequency circuits.
Main performance: EMI materials rely on magnetic and electrical losses to absorb electromagnetic energy and interfere with electromagnetic waves. Therefore, they generally require high impedance under conditions of 10-100MHz and are generally used for magnetic beads.
