Molded inductor structure is different from other types of magnetic devices. Molded inductors are manufactured by compressing a magnetic material in a mold using an adhesive or polymer, and compressing the magnetic material around a conductive air coil to form an integrated structure. The magnetic material used in this process is a soft magnetic atomized powder. The compressed structure is cured in an oven to form a solid composite structure. The use of adhesives/polymer materials serves to distribute the gaps and thus enhance the magnetic properties. The binder/polymer composition used in the product encapsulates the composite materials' powder, which helps to block the part from becoming magnetic and prevents the part from oxidizing in a humid environment.
