Amorphous & Nanocrystalline Cores for High-Performance Common Mode Chokes

FERRTX offers advanced Amorphous and Nanocrystalline Cores specifically engineered for high-efficiency Power Line Common Mode Choke applications. Thanks to their ultra-low coercivity, high permeability, and excellent frequency response, these magnetic materials deliver superior suppression of common-mode noise in compact designs.

Compared with traditional ferrites, our cores provide higher impedance and improved thermal stability—making them ideal for modern SMPS, EV chargers, renewable energy systems, and compact EMC modules.

This page focuses on the newly separated product category for Common Mode Choke Cores, offering a clearer and more targeted structure than the previous combined Amorphous Core listings.

Amorphous vs Nanocrystalline Cores — What’s the Difference?

Choosing the right material is critical for EMI and power electronics design. Understanding amorphous vs nanocrystalline cores helps engineers optimize performance.

amorphous cores

• Wide frequency response

• Good temperature performance

• Lower cost compared with nanocrystalline

• Ideal for mid-range EMI suppression

Nanocrystalline Cores

• Much higher permeability

• Higher attenuation in compact dimensions

• Excellent stability under high current

• Preferred for premium Power Line Common Mode Choke designs

FERRTX provides both materials to cover the full spectrum of EMI filtering needs.

Key Features & Benefits

• High Permeability Materials
  Excellent suppression of common-mode interference, even in compact winding windows.

• Lower Core Losses
  Nanocrystalline Cores offer exceptionally low losses under high-frequency operation.

• Stable Performance at High Temperatures
  Supports applications up to 120–150°C depending on material grade.

• Reduced Size & Weight
  Higher permeability allows smaller chokes with equivalent filtering capability.

• Optimized for High-Reliability Designs
  Suitable for industrial, automotive, and renewable power systems.

Typical Applications

• Power Line Common Mode Choke
  (SMPS, adapters, LED drivers, telecom power, industrial control)

• EV onboard chargers

• PV inverter and wind power converters

• UPS and energy storage systems

• High-current DC/DC converters

• Home appliances and smart meters
