COIL COMPONENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18039650 titled 'COIL COMPONENT
Simplified Explanation
The coil component described in the patent application includes a coil, a first core with a high magnetic permeability, and a second core with a lower magnetic permeability than the first core. The first core and second core create a magnetic path, and the coil has multiple winding windows. The first core contacts one side line of each winding window and protrudes from at least one side line of one of the windows, while the second core contacts three side lines of each window. The first core has a surface resistance of at least 5 Ω between two points 20 mm apart after a high-temperature storage test, and the drive frequency of the coil component is at least 20 kHz.

Original Abstract Submitted
The coil component includes a coil, a first core having a first magnetic permeability, and a second core having a second magnetic permeability lower than the first magnetic permeability. The first core and the second core form a magnetic path. The coil forms two or more winding windows. The first core contacts with an entirety of one side line extending in a second direction of each of the winding windows, and protrudes from both ends of one side line of at least one of the winding windows. The second core contacts with three side lines other than the one side line of each of the winding windows. A surface resistance of the first core between two points that are 20 mm away from each other is not less than 5 Ω after a high-temperature storage test. A drive frequency of the coil component is not less than 20 kHz.
