Ferrocore T6x4x3 parts are cylindrical ferrite cores made from soft ferrite material. They primarily consist of magnetic oxide powders and binder and are used for inductors, transformers, and EMI suppressors. The cylindrical T6x4x3 dimensions refer to the length and diameter of the ferrite core, both of which measure 6mm and 4mm respectively. The 3mm is the core's thickness. The ferrite core has good electrical and magnetic properties and has very high saturation flux density, making them suitable for high frequency and high power applications. Additionally, they are non-oriented, non-magnetic, and have a low core loss at low frequencies.
