Mn-Zn FERRITE WITH HIGH INITIAL PERMEABILITY

摘要

PROBLEM TO BE SOLVED: To provide an Mn-Zn ferrite with high initial permeability having both high initial permeability μ_i and excellent mechanical strength.;SOLUTION: In the Mn-Zn ferrite mainly containing a ferric oxide, manganese oxide and zinc oxide, initial permeability μ_i at 1 kHz and 23°C is specified to be 26,000 or higher, and an average crystal grain size D is specified to be 17 μm ≤ D 50 μm.;COPYRIGHT: (C)2005,JPO&NCIPI
