High-Purity Magnetic Iron Silicon Alloy (FeSi) Powder Core

Ultra-Low Core Loss & High Permeability
Precisely engineered with 6.5% silicon content for minimized eddy current loss, delivering superior DC bias performance (up to 80% at 100 Oe). Ideal for high-frequency inductors and PFC chokes.
Controlled Particle Size Distribution (50-150μm)
Gas-atomized spherical powder ensures uniform density and reduced air gaps, enhancing saturation flux density (1.6T) for stable operation in EV charging systems and solar inverters.
Multi-Layer Insulation Coating
Phosphate-based layer provides >500V dielectric strength, preventing inter-particle short circuits in high-power SMPS and industrial UPS applications.
Customizable Shapes & Grades
Available in toroid, E-core, and block configurations (0.5mm-25mm thickness) with optional Ni-Zn coating for extreme corrosion resistance in marine electronics.
Batch-Certified Consistency
Each lot undergoes ASTM A34-03 testing with <2% μ-r variance, ensuring reliability for 5G base stations and wireless charging modules.
Global Bulk Supply Advantage
Direct-from-factory pricing at 30% below market average for 100kg+ orders, with ISO 9001-certified production lines.
Applications:
- High-efficiency transformers (100kHz-1MHz) - EMI filter cores for aerospace electronics - Precision sensors and actuator drives
