Nanocrystalline C Cores

Hitachi finemet f3cc0050 nanocrystalline core

Nanocrystalline C core is upgrade product of amorphous c core, with high saturation flux density, low coercivity, low core loss, very low noise, higher frequency up to 20KHz, suitable for main power transformer, audio transformer, output inductor, boost PFC choke coil. Can replace ferrite cores, permalloy cores, silicon steel cores. Dimensions can be custom-made.
