Nanocrystalline Cores and Bead Cores

Epoxy Coated Nanocrystalline Cores and Bead Cores

Ferrite - Nanocrystalline Cores

Compact, high-performance solutions for EMI suppression, power transfer, and signal integrity

TI-Electronic’s epoxy coated nanocrystalline cores and bead cores combine outstanding magnetic performance with mechanical flexibility. The epoxy coating enables custom shapes and dimensions without additional tooling costs, making them ideal for rapid prototyping and cost-efficient manufacturing.

These components offer high permeability, small size, and strong electrical insulation, making them suitable for a wide range of applications including surge suppression, signal isolation, and power conversion.

✨ Key Features

  • Miniature form factor: Compact size reduces total device volume

  • Epoxy insulation: Eliminates the need for molding, supports custom shapes

  • Core volume reduction: Less copper wire, lower total material cost

  • High insulation strength: Withstands up to 1000V

  • High permeability: Inductance up to 3x higher than ferrite cores

🌋 Typical Applications

  • Surge suppression beads (e.g. for MOSFET snubbers)

  • IGBT driver transformers

  • High-frequency transformers and gate drivers

  • ISDN/network signal transformers

  • EMI/EMC common mode chokes

  • HD camera and signal isolation transformers

  • Precision current transformers

These components are ideal for engineers seeking cost-effective, high-insulation, and magnetically efficient designs.

🔧 Technical Advantages

  • High-frequency performance suitable for power and signal systems

  • Epoxy coating ensures safe handling and environmental resistance

  • Custom sizes can be delivered with short lead time and no tooling charges
