High Flux Cores: Engineered Stability for Extreme DC Bias Conditions

Core Technology Breakthrough

High flux cores revolutionize magnetic material performance with patented alloy composition, delivering unmatched stability where conventional solutions fail. Unlike standard ferrite cores that degrade rapidly above 30 Oe, our powder alloy technology provides:

• 90% permeability retention at 50 Oe (verified per page 2 DC bias curves)
  
• Military-grade temperature resilience (-55°C to +125°C operating range)
• Precision μ-range (14μ to 125μ) for tailored inductance control

Designer Insight: When developing compact Power Inductors for EV fast-charging systems, the 90% permeability retention at 50 Oe enables 22% smaller form factors versus alternatives.
