UU - UR Cores

Bunting Magnetics Europe > Soft Magnetics > Soft Ferrites > Components > UU – UR Cores

These cores are used to construct transformers in the frequency range from 10 to 500 kHz. The transferable outputs will be determined by core geometry and the upper-frequency limits by the material selected. In previous years, a significant application was for in-line transformers producing an electron deflection beam for CRTs. Materials used for these applications are characterized by high flux density, low specific power losses and the decline of losses dependent on temperature from 20°C to 100°C.
