Super Flux Core Series are made of special high purity iron-alloyed powders which show much lower core loss than any iron powder cores but a little higher than Sendust cores. Although MPP cores have very low core loss, they have only flux of 7800 Gauss (Bs), which restricts MPP cores for high current applications. Besides, MPP cores are only good up to 300 KHz frequencies; if you meet applications for high current or high frequency up to 2.5MHz, please select Super Flux Core Series.

Most important Super Flux Core Series are much inexpensive than Sendust cores and MPP cores. In addition, Super Flux Core Series are available to be formed with various shapes and sizes.
