Abstract

The invention provides a laminated chip inductor. The laminated chip inductor comprises a magnet; two external electrodes which are arranged at the two ends of the magnet; and a plurality of inner electrodes which are respectively arranged in the magnet, wherein two ends of each inner electrode are respectively connected with the two outer electrodes. According to the embodiment of the invention,the plurality of inner electrodes are arranged between the two outer electrodes, and the two ends of each inner electrode are respectively connected with the two outer electrodes, so that the plurality of inner electrodes are connected in parallel between the two outer electrodes, the resistance between the two outer electrodes can be reduced, and the Q value of a product is further improved. Thus, the Q value of the product is greatly improved by reducing the resistance between the two outer electrodes, the thickness of a single inner electrode does not need to be greatly increased, the problem that the single inner electrode is prone to collapsing during machining after the thickness of a wire is increased is solved, machining of the inner electrode wire is controlled, product deviationis prevented, and product stability is guaranteed.

Description

technical field [0001] The present application belongs to the technical field of inductors, and more specifically relates to a laminated chip inductor. Background technique [0002] In the impedance matching or high-order harmonic trap circuit, the multilayer chip inductor is required to have a high quality factor (QualityFactor, referred to as Q) in addition to the appropriate inductance and self-resonant frequency. The Q value is an important index to measure the inductor. It represents the ratio of the inductive reactance presented by the inductor to its equivalent loss resistance when it works under an AC voltage of a certain frequency. Although the Q value of the inductor is related to the inductance, but It is also affected by the stray capacitance introduced by the inductor itself and during assembly, and the resistance of the electrodes inside the inductor. [0003] An existing multilayer chip inductor is to reduce the resistive loss of the internal electrode by inc...
