High Flux Cores

High Saturation Flux Density for High Power Applications

High Flux cores have saturation flux density that is twice that of MPP and three times or more that of ferrite. As a result, High Flux cores can support significantly more DC bias current or AC flux density. The high saturation flux density (15,000 gauss) and relatively low losses of High Flux cores make them quite useful for applications involving high power, high DC bias, or high AC bias at high power frequencies such as Switching Regulator Inductors, In-Line Noise Filters, Flyback Transformers, Power Factor Correction (PFC), and Pulse Transformers.
