纳米晶C型磁芯

Nanocrystalline c cores

Nanocrystalline C core is available now. 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, output inductor, boost PFC choke coil. Can replace ferrite core. Dimensions can be custom-made.
