Cores have lower losses at high frequencies
Chang Sung Corp of Korea offers a complete range of toroids in MPP, high-flux and Sendust powder materials manufactured to the highest specifications.
High-flux cores have certain advantages that make them quite useful for applications involving high power, high DC bias, or high AC bias at high power frequencies.
High-flux cores have a saturation flux density of 1.5T, compared to 750mT for standard MPP cores or 450mT for ferrites.
The core loss of high-flux powder cores is significantly lower than that of powdered iron cores, and so a smaller core can be used in most applications.
The cores are available with outside diameters ranging from 3.5 to 78.9mm, with initial permeability from 26 to 160u.
High-flux cores are ideal for use in low-loss chokes for switch-mode power supplies, switching regulators, noise filters etc.
