High Flux Cores

High Flux cores offer the highest biasing capability of all powder core materials. 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.

Large Powder Core Toroids

Five large sizes have been added to the High Flux toroids, including the massive 165 millimeter core. Large Powder Core toroids are a cost-effective option for high current applications, such as: UPS, large Power Factor Correction (PFC) chokes and inverters for renewable energy.
