摘要
综述了近两年来世界各大公司锰锌铁氧体材料技术特性日新月异的进步,指出了该材料系列三大板块(高μ、高Bs、低功耗、高μQ)相互交叉,求新求全发展的动向,总结了新材料两宽(宽温、宽频)、两高(高饱和磁通密度,高直流叠加性能)、两低(低损耗或低功耗、低谐波失真)的技术特点,提出了以现有材料体系为基础的研发思路。
In this paper, the latest development of Mn-Zn ferrites of some main enterprises in the world was summarized. This material series mainly has three types: high permeability, high Bs , low power loss and high μ Q, which are cross each other. The main characteristics of their development are “two wide” (wide temperature range, wide frequency range), “two high” (high Bs, high DC-bias performance) and “two low” (low loss, low total harmonic distortion). In addition, the developing direction of Mn-Zn ferrite is proposed based on the existing Mn-Zn ferrite.
