Nanocrystalline C Cores for High Frequency

Nanocrystalline C Cores for High Frequency Applications

Premium magnetic performance for precision and efficiency in compact designs

TI-Electronic’s Nanocrystalline C Cores are the superior choice for high-frequency magnetic applications requiring top-tier efficiency, low loss, and minimal noise. Manufactured from nanocrystalline ribbon, these cores offer better magnetic performance and thermal stability than standard amorphous C cores.

✨ Key Benefits

  • Superior to amorphous cores: Higher saturation induction and permeability

  • Low core loss: Ideal for 20–30 kHz switching frequencies

  • High saturation induction (1.25 T): Operates well above ferrite performance levels

  • Low magnetostriction: Enables quiet operation with reduced audible noise

  • Energy-efficient design: Supports compact, high-performance transformer builds

🌋 Typical Applications

  • High-frequency transformers (main, auxiliary, gate drive)

  • Premium audio transformers

  • PFC chokes and output filter inductors

These cores excel in demanding environments where both electrical efficiency and thermal reliability are critical.

🔌 Why Choose Nanocrystalline C Cores?

Compared to traditional magnetic core materials:

  • Offer lower core loss for improved energy efficiency

  • Handle higher current densities without saturation

  • Deliver stable performance in thermally stressed conditions

  • Provide excellent performance in audio-sensitive systems

🔧 Technical Overview

  • Frequency range: Optimized for 20–30 kHz applications

  • Saturation flux density: 1.25 Tesla

  • Core loss: Significantly lower than ferrite at switching frequency

  • Magnetostriction: Very low, minimizing mechanical hum or vibration

  • Construction: Precision-cut nanocrystalline strip, C-shaped profile

🚚 Custom Solutions Available

TI-Electronic offers an extensive selection of standard sizes and also supports:

  • Custom dimensions

  • Special mechanical mounting needs

  • Application-specific insulation or coating
