外部直流磁场对多层陶瓷电容器高频阻抗特性的影响

Multilayer ceramic capacitors (MLCCs) are widely used in power electronics. Because paraelectric and ferroelectric material are nonmagnetic dielectrics, B-field effects are typically ignored in datasheets and design consideration. This letter reveals a significant, previously undocumented phenomenon: B-fields cause substantial high-frequency impedance variation in MLCCs, with observed changes exce...
