Ferroxcube ferrite materials - high-performance ceramic magnets for modern electronics

Available from Megatron - your specialist for high-quality magnetic materials

Ferroxcube ferrites are ceramic magnetic materials that are indispensable in many areas of modern electronics. They are characterized by low magnetic losses, high thermal stability and excellent adaptability - ideal prerequisites for energy-efficient and high-performance applications.

As a distribution partner of Ferroxcube, Megatron offers a wide range of ferrite materials for developers and manufacturers in power electronics, telecommunications, lighting technology and more. From standard solutions to customized materials, Megatron supports its customers with technical expertise and reliable service.

 

Main features and properties

1. material composition

Ferroxcube ferrites consist of iron oxide combined with metal oxides. Two main types:

  • MnZn ferrites (manganese-zinc): High permeability, high saturation induction

  • NiZn ferrite (nickel-zinc): Lower losses at high frequencies

2. magnetic properties

  • Low core losses

  • Temperature stable up to over 100 °C

  • High saturation induction - ideal for high-performance applications

3. frequency ranges

  • NiZn ferrites: Optimal for frequencies above 1 MHz

  • MnZn-Ferrite: Suitable for frequencies up to 3 MHz with high energy transmission

Typical areas of application

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

  • Telecommunications: high-frequency filters, antennas

  • Lighting technology: LED drivers, electronic ballasts

  • EMC suppression: common mode and differential mode chokes

  • Power distribution: current sensors, high-power transformers
