HIGH-CURRENT THIN INDUCTOR AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To utilize the space required for making an inductor to exert its performance to the utmost by forming a magnetic material of first and second powdery steel materials and forming the main body of the inductor by bonding the first and second materials to each other under pressure. SOLUTION: The main body 14 of an inductor is constituted by completely surrounding a wire coil 24 with a magnetic material. Each end 26 of a first coil is connected to a first lead 16 in the main body 14 and each end 28 of a second coil is connected to a second lead 18 in the main body 14. The leads 16 and 18 are extended to each section of the main body 14 through the main body 14. The magnetic material is composed of first and second powdery steel materials having different electrical characteristics and the main body 14 is formed by bonding the first and second materials to each other under pressure so that the size of the inductor can be minimized.
