Today I will briefly introduce the difference between manganese zinc and nickel zinc in ferrite core.

　　First of all, we should know that manganese core is mainly made of high sensitivity, nickel core is made of low sensitivity.

　　Due to the particularity of its metal composition, manganese zinc material is widely used in common-mode inductors, and its sensing value is relatively high. Generally speaking, the sensing value is millihen level, ranging from a few millihen to dozens of millihen.

　　The sensory value of nickel zinc material is relatively low, generally are micro Heng level.

　　Manganese zinc and nickel zinc are generally based on their own impedance. The impedance of manganese zinc is relatively low, about 103Ω·cm below; The impedance of nickel zinc is relatively high, about 105~108Ω·cm.

　　Their permeability varies depending on their metal composition. The permeability of manganese zinc is relatively high, and that of nickel zinc is relatively low.

　　Manganese zinc and nickel zinc have different uses because of their different materials. Manganese zinc is mainly used in transformer, local area network and other fields; Nickel and zinc are mainly used in computer, radar, television and other fields.

　　Their common feature is that they have better filtering effect.

　　Manganese zinc and nickel zinc are also used at different frequencies. The use frequency of manganese zinc is lower than that of nickel zinc, its frequency is generally in a few KHz~ several hundred KHz; The nickel-zinc frequency ranges from 1MHz to several hundred MHz, and in some special areas, the nickel-zinc frequency can even reach thousands of megabits.
