Nanocrystalline Material Cores

At TI-Electronic, we are also specialists in the production of cores made from nanocrystalline materials. These materials allow us to produce inductive elements that meet the ever-growing demands of frequency and operating temperature in modern electronics.

Key Features of Nanocrystalline Cores:

  • High-frequency performance: Metal-metal type nanocomposites can be used up to 10 MHz, while metal-insulator nanocomposites operate up to GHz range frequencies.
  • Versatile permeability: Through specialized heat treatment, the permeability of our nanocrystalline cores can be adjusted between 25,000 and 90,000, allowing for highly customizable applications.
  • Wide application range: Our cores are suitable for switch-mode power supplies, current meters, and other electronic systems requiring low permeability and linear magnetization.

Currently, we focus on producing metal-metal nanocomposites, specifically nanocrystalline alloys. These alloys are made by heat-treating amorphous structures, which are produced by rapid cooling. We can produce amorphous tapes in widths between 4 and 20 mm, and larger cores are created by stacking thinner cores together.

Fe-based nanocrystalline material with composition of mostly Fe with Cu,Nb,Si,B, which first by rapid quenching technology to form amorphous ribbon, then by crystalline heat treatment to gain fine grains with nano scale. Through this revolutionary process, we can get superior magnetic properties with high saturation flux density, high initial permeability, low coercivity, low core loss. Nanocrystalline material is an environmental protection, green, low carbon,high efficiency new magnetic material.

Nanocrystalline Product Family

Nanocrystalline cores for EMC common mode chokes

✅ Overview – Nanocrystalline Cores for EMC Common Mode Chokes

  • ✔️ Ultra-high permeability – wideband noise filtering from 1 kHz to 10 MHz

  • ✔️ High inductance in small size – 2–3× better performance than ferrite

  • ✔️ Lower winding count – reduces copper usage and core losses

  • ✔️ High Curie temperature (560 °C) – stable up to 120 °C continuous use

  • ✔️ Applications:
    – EMC filters and common mode chokes
    – SMPS, server and computer power supplies
    – Solar & wind power inverters
    – EV chargers, UPS, VFDs, servo motors
    – Laser/X-ray power and industrial electronics

📌 Nanocrystalline cores are the preferred material for high-performance common mode chokes due to their superior EMI suppression, thermal stability, and compact size.

🛠 Custom sizes and epoxy coating options available.

✅ General-Purpose Current Transformer Cores:

(Compared to precision CT cores)

  • Designed for current sensing, not precision metering

  • Used in industrial equipment, UPS, EV chargers, inverters, etc.
