Nicuzn based ferrite and electronic component using the same

Abstract

An NiCuZn-base ferrite of the invention comprises as main components an iron oxide in an amount of 45.0 to 49.0 mol % on Fe2O3 basis, an copper oxide in an amount of 5.0 to 14.0 mol % on CuO basis and a zinc oxide in an amount of 1.0 to 32.0 mol % on ZnO basis with a nickel oxide accounting for the rest mol % on NiO basis. With respect to the main components, a bismuth oxide is contained in an amount of 0.25 exclusive to 0.40% by weight on Bi2O3 basis, and a tin oxide is contained in an amount of 1.00 to 2.50% by weight on SnO2 basis. The invention ensures a leap upward in direct-current bias characteristics.

Description

technical field

[0001] The present invention relates to a NiCuZn-based ferrite, and an electronic component manufactured using the same. In particular, it relates to a ferrite used as a material of an electronic component forming a closed magnetic circuit, and an electronic component manufactured using the same. Background technique

[0002] So far, ferrite, as a magnetic material containing oxides such as Ni, Cu, and Zn, has been used as a core (magnetic core) material for various electronic components, or a laminated chip inductor, etc., due to its excellent magnetic properties. Materials for inductor parts, etc.

[0003] Considering that this magnetic core or inductor component will be used in various temperature environments, it is required that the rate of change of the initial magnetic permeability μi relative to the temperature change is small, that is, the temperature characteristic of the initial magnetic permeability μi is good (relative to the temperature little ...
