E-cores, U-cores and i-cores

E-cores, U-cores and i-cores

These devices consist of ferrite and form the core of small power transformers, transmitters and choke coils. This is because the material characteristics of ferrite enhances the inductance value or strength of the magnetic field of the E-cores, U-cores and i-cores. In addition to the U-cores, i-cores are necessary for the structure of power transformers and power transmitters. U-cores are required for power transformers with powers in excess of 1 kW and for power transmitters. There power capacities depend on the core geometry. Further fields of application of U-cores are line transformers for deviation of the electron beam in image tubes, or ignition coils in the automobile industry.
