MPP Cores

MPP cores possess many outstanding magnetic characteristics, such as high resistivity, low hysteresis and eddy current losses, excellent inductance stability after high DC magnetization or under high DC bias conditions and minimal inductance shift up to 2000 gauss under AC conditions. Applications for MPP cores include; Flyback Transformers, Buck/Boost and Power Factor Correction (PFC), Inductors, In-Line Noise Filters, High Q Filters, and Resonant Circuits.
