3E65 Datasheet, PDF (3/8 Pages) Ferroxcube International Holding B.V. – Medium permeability High Curie Temperature High Saturation Flux Superior EMI ferrite material

3E65
Ferroxcube 3E65 is a medium permeability ferrite material optimized for Common Mode Electro Magnetic
Interference (EMI) suppression. Its frequency stability allows the designer to attenuate noise over the
complete conducted EMI frequency band up to 30 MHz.
Increased Curie Temperature (Tc, highest temperature at which the material shows its magnetic properties) is
well suited for high temperature application segments, such as automotive, industrial and renewable energies.
Maximum magnetic flux density (Bsat) is also higher than in standard medium permeability ferrite materials,
improving the EMI suppression capability under inrush currents or non-compensated currents.
3E65 Specifications
A medium permeability material with low losses and high Tc, optimized for use in wideband
transformers as well as EMI-suppression filters.
