The Principles of Using and Selection Methods of Ferrite Core

For soft magnetic ferrite, magnetic permeability is usually desired μ I and resistivity ρ To be high, the coercivity Hc and loss Pc should be low. According to different usage, there are also different requirements for the Curie temperature, temperature stability, magnetic permeability reduction coefficient, specific loss coefficient, etc. of the material.

Which Is More Advantageous between Molding Powder Inductor and Wire Wound SMD Power Inductor

The materials and production processes are different. The integrated inductor is made by die-casting the base of the winding body embedded in metal magnetic powder, and the surface packaging pin is the lead out pin of the winding body directly formed on the surface of the base body. However, for ordinary power chip inductors, copper wire is wound around the magnetic core and then sealant is applied.

The Features and Applications of Ferrite Beads Core

Ferrite magnetic bead suppression components are also widely used in printed circuit boards, power lines, and data lines. If a ferrite suppression component is added to the power line inlet of the printed circuit board, high-frequency interference can be filtered out.
