Ferroxcube Ferrite Materials – Ceramic Magnets for Electronics

Ferroxcube ferrites are ceramic magnetic materials used in numerous electronic applications. They are characterized by high thermal stability, low magnetic losses, and good adaptability to specific requirements. Typical applications include power electronics, telecommunications, and lighting technology – wherever efficient energy conversion, signal transmission, and a stable power supply are required.

Important properties and features

composition
Ferrites consist of iron oxide combined with one or more metal oxides. Commonly used systems are manganese-zinc (MnZn) and nickel-zinc (NiZn).

Magnetic properties
Ferrites offer high saturation induction, low losses, and temperature stability. They are particularly suitable for high-current applications.

Frequency ranges

  • NiZn ferrites : For frequencies above 1 MHz

  • MnZn ferrites : For frequencies up to 3 MHz with higher permeability and saturation induction

Application areas

  • Power electronics: switching power supplies, DC/DC converters, inverters

  • Telecommunications: high-frequency filters, antennas

  • Lighting technology: ballasts, LED drivers

  • EMC suppression: common-mode and differential current filters

  • Power generation and distribution: current transformers, power transformers

Individual customization

Ferroxcube offers a wide range of ferrite materials that can be customized to meet specific technical and industry requirements.

Production

Production takes place in several steps: mixing, calcining, fine grinding and pressing of the raw materials, followed by sintering and post-processing.
