High Flux cores offer one of the highest biasing capabilities of all powder core materials. The high saturation flux density (15,000 gausses) and relatively low losses make High Flux cores 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.
