Amorphous C Cores for Power Transformers

Amorphous C Cores for Power Inductors and Transformers

Amorphous C cores dimensions

High-efficiency cores for compact and thermally stable designs

TI-Electronic’s Amorphous C Cores are engineered for high-performance power inductors and transformers where DC bias tolerance, low loss, and compact size are essential. These cores are ideal for PFC chokes, solar inverter reactors, filter inductors, and audio transformers, especially in applications operating at medium to high frequencies.

✨ Key Features

  • High saturation flux density: Withstands large DC bias without early saturation

  • Low core loss: Reduces temperature rise and improves system reliability

  • High permeability: Efficient magnetic response, even at elevated frequencies

  • Compact size: Enables reduced copper use and footprint

  • Robust design: Suitable for continuous industrial use

🌋 Typical Applications

  • Power Factor Correction (PFC) inductors

  • Output filter inductors

  • Solar inverter reactors

  • High-current line/load reactors

  • Audio-grade transformers

These C cores are widely used in power electronics, renewable energy systems, industrial drives, and precision analog systems.

🔌 Benefits Over Traditional Materials

Compared to ferrite or silicon steel:

  • Higher saturation point allows higher DC currents

  • 70%+ lower core loss at switching frequencies

  • Better thermal stability and longer service life

  • Enhanced performance in compact magnetic assemblies

🔧 Technical Specifications

Available in a wide range of dimensions and magnetic profiles. Custom sizes and epoxy coatings available upon request. These cores are precision-cut and finished for optimal performance and easy integration.

  • Saturation flux density: High, suitable for heavy load handling

  • Temperature stability: Continuous operation up to 120 °C

  • Frequency range: Medium to high (up to 100 kHz typical)

  • Construction: Laminated amorphous metal, precision C-shaped core
