Description

Technical Field

[0002] A chip inductor, also known as a surface mount inductor, like other chip components, is a new generation of leadless or short-lead microelectronic components suitable for surface mount technology. The welding surface of its lead-out terminals is on the same plane. The stacked chip inductor has a small volume, which is beneficial to the miniaturization of the circuit. And its magnetic circuit is closed, so it will not interfere with other surrounding components. At the same time, the stacked chip inductor itself will not be interfered by adjacent components, which is beneficial to the high-density installation of components. It has an integrated structure, greatly reducing the space volume. And the stacked inductor has high reliability, strong high-temperature heat resistance, good solderability, regular shape and volume, which is conducive to automatic production and installation machinery and equipment.

[0003] Usually, the electrode plates of chip inductors are exposed. When not in use, they are easily touched by other objects, which will cause scratches on the surface of the electrode plates, easily reduce the performance of the inductor and shorten its service life. Therefore, we propose a stacked chip inductor with a protection structure to solve the problems mentioned above. Content of the Utility Model
