Abstract

Provided in the present invention are a power inductor and a method for manufacturing same, the power inductor comprising: a body; a substrate provided inside the body; a coil formed on top of the substrate; first external electrodes which are connected to the coil and provided on the sides of the body; and second external electrodes which are connected to the first external electrodes and provided on the bottom surface of the body.

Description

technical field [0001] The present disclosure relates to a power inductor, and more particularly, to a power inductor capable of preventing short circuits with peripheral devices and a method of manufacturing the same. Background technique [0002] Power inductors are generally provided on power circuits such as DC-DC converters provided in portable devices. Due to the trend toward high frequency and miniaturization of power circuits, power inductors are increasingly being used to replace existing wound-type choke coil patterns. Also, miniaturized, high-current, and low-resistance power inductors are being developed because small and multifunctional portable devices are required. [0003] Power inductors can be fabricated in the form of stacked bodies of ceramic sheets formed from various ferrites or low-k dielectrics. Here, a metal pattern is formed on each of the ceramic sheets in a coil pattern shape. The coil patterns formed on the ceramic sheets are connected to each...
