Problems solved by technology

[0003] The applicable frequency range of existing nickel-zinc magnetic materials is not wide enough, and it has high impedance in the frequency range of 1MHz to 10MHz or 50MHz to 100MHz, but it cannot meet the requirements of high impedance from 1MHz to 100MHz at the same time.
When the frequency of use changes, another material must be used to re-produce the applicable device at this frequency, which increases the cost

Abstract

The invention discloses a nickel-zinc magnetic material formula applicable in a wide frequency range; the formula is composed of the following raw materials by mass: 65.0-67.0% of ferric oxide, 10.5-13.0% of nickel protoxide, 18.0-20.3% of zinc oxide, and 4.0-5.0% of copper oxide. According to the nickel-zinc magnetic material formula applicable in the wide frequency range, the ratios of various main element atoms in ferrite crystals are changed, a produced nickel-zinc magnetic material is superior to a conventional nickel-zinc magnetic material, has relatively high impedance in the range of 1 MHZ to 100 MHZ, expands the use frequency range of devices, and reduces the cost; and the nickel-zinc material is small in size, light in weight and wide in application.

Description

technical field [0001] The invention relates to the field of soft magnetic ferrite materials, in particular to a nickel-zinc magnetic material formula applicable in a wide frequency range. Background technique [0002] Soft magnetic ferrite material is a kind of material with the earliest development, the widest application, more varieties and higher output among ferrites. Among the various soft ferrite materials, nickel-zinc magnetic materials have excellent broadband characteristics, making them widely used in related technical fields such as digital communication, optical fiber communication, network, and electromagnetic compatibility. Nickel-zinc magnetic materials are mainly used in electronic components such as inductors, transformers, antenna rods, flyback transformers, suppression rings, choke coils and recording heads. The wider the applicable frequency range of various electronic components and the wider the application area, the lower the cost of use. Therefore, ...
