How to choose the core of the integrated inductor? - Focus on microfluidic control technology

The fabrication of the integrated inductor is decisive for the choice of the core. The following explains the Mn-Zn core of the inductor and its advantages:
The Mn-Zn core is a soft magnetic core with a high initial permeability. The surface resistance of the product is low, and the higher the initial permeability, the lower the surface resistance. Therefore, it is generally used in circuits below 1 MHz.
Main use: The initial magnetic permeability of the material is generally around 2000~3000, with high saturation magnetic flux density and low loss. It is one of the most ideal power inductor cores around 100KHz.
The nickel-zinc core is a soft ferrite core. The nickel-zinc core generally has an initial magnetic permeability of 5 to 1500. Due to its high surface resistance, the core is generally used in medium and high frequency circuits.
Main performance: EMI materials rely on magnetic losses and electrical losses to absorb electromagnetic energy to absorb electromagnetic waves. Therefore, it is generally required to have higher impedance at 10~100MHz, which is generally used for magnetic beads.
