COIL PARTS

摘要

PURPOSE: A coil component is provided to improve a filtering property by smoothly increasing the flow of a magnetic flux and to reduce a manufacturing cost by shortening the length of a coil pattern. CONSTITUTION: A coil body(110) includes a primary coil pattern(111) formed into a spiral form, a secondary coil pattern(112), and a dielectric including the primary coil pattern and the secondary coil pattern. A bottom magnetic body(120) is formed of a ceramic board formed of a ferrite material and the coil body is installed on the bottom magnetic body through a thinning process. A central part(110a) and an outer part of the coil body is filled with of A top magnetic body(130) and included in the top of the bottom magnetic body to cover an insulator(113).
