COIL COMPONENT - A simplified explanation of the abstract

• This abstract for appeared for US patent application number 18189725 Titled 'COIL COMPONENT'

Simplified Explanation

The abstract describes a coil component that consists of an element assembly and an outer electrode. The element assembly includes a coil conductor, which is a conductor coated with an insulating film, and a magnetic portion made of metal magnetic particles and resin. The outer electrode is electrically connected to the exposed surface of the extended part of the coil conductor. The metal magnetic particles in the magnetic portion have a particle size distribution with at least two peaks and at least one minimum point. The larger magnetic particles are equal to or larger than the minimum point with the lowest frequency.

Original Abstract Submitted

A coil component includes an element assembly including a coil conductor formed by winding a conductor coated with an electrically insulating film and a magnetic portion containing metal magnetic particles and resin, and an outer electrode electrically connected to an exposed surface of an extended part of the coil conductor, exposed on a surface of the element assembly and disposed on the surface of the element assembly. The metal magnetic particles include first and second metal magnetic particles. A particle size distribution of the metal magnetic particles, calculated in accordance with a circle equivalent diameter obtained from a cross-sectional image in a cross section of the magnetic portion, has at least two peaks and at least one bottom. The large magnetic particles are larger than or equal to the bottom having a minimum frequency.
