Coil component with drum core and terminal electrode
A recently granted patent (Publication Number: US11923118B2) discloses a coil component designed with specific features to enhance its performance. The coil component includes a drum core with a winding core portion and flange portions at both ends. The terminal electrode on the flange has multiple metal layers, with the outermost layer being an Sn film with a flattened mounting surface that overlaps a step in the flange when viewed from a perpendicular direction. The design also includes inner and outer curved surface portions adjacent to the step, with specific dimensions and configurations to optimize functionality.
Furthermore, the patent details variations in the design, such as different radius of curvature for the inner and outer curved surface portions, multiple steps on the flange, and specific height and width measurements for the flattened mounting surface. The coil component is structured to ensure efficient wire winding around the core portion, with the terminal electrode providing a secure connection. The use of Ni/Cu plating for the metal layers of the terminal electrode further enhances the performance of the coil component. Overall, the patented coil component showcases innovative design elements aimed at improving the functionality and effectiveness of such components in various applications.
