AI Technical Summary

Technical Problem

As electronic devices become more high-performance and miniaturized, the demand for inductors is increasing. Existing inductors are inadequate in terms of vibration resistance and heat dissipation, especially in electronic devices used in vehicles, where improved vibration resistance and heat dissipation are needed.

Method used

A coil assembly was designed with a body having a decahedral shape, a first inclined surface and a second inclined surface with the side surfaces inclined in different directions, and deep recesses formed on the surface to increase the surface area to improve heat dissipation performance. At the same time, the structure design of the external electrodes enhances vibration resistance.

Benefits of technology

It improves the vibration resistance and heat dissipation performance of coil assemblies, adapting to the high performance and miniaturization requirements of electronic devices, especially exhibiting excellent vibration resistance and heat dissipation in electronic devices used in vehicles.
