用于高频变压器它是一种带有尖晶石结晶状结构的陶磁体，此种尖晶石为氧化铁和其它二价的金属化合物。如kFe2O4(k代表其它金属)，目前常使用的金属有锰(Mn)、锌(Zn)、镍(Ni)、镁(Ng)、铜(Cu)。
For high frequency transformer, it is a ceramic magnet with spinel crystal structure, which is iron oxide and other bivalent metal compounds. For example, kfe2o4 (k represents other metals), the commonly used metals are manganese (MN), zinc (Zn), nickel (Ni), magnesium (NG), and copper (Cu).
其常用组合如锰锌(Mn Zn)系列、镍锌 (Ni Zn)系列及镁锌(Mg Zn)系列。此种材具有高导磁率和阻抗性的物性，其使用频率范围由1kHz到超过200kHz。
Its common combinations are manganese zinc (Mn Zn) series, nickel zinc (Ni Zn) series and magnesium zinc (mg Zn) series. This kind of material has the physical properties of high permeability and impedance, and its frequency range is from 1kHz to over 200kHz.
