Amorphous C Cores for Power Inductors and Transformers

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
