XFLUX Cores

XFLUX® cores offer an economical high saturation (1.6 Tesla) solution for use in low and medium frequency inductors and chokes. The high saturation is advantageous in applications where inductance under load is critical such as inverters for alternative energy, Power Factor Correction (PFC) boost, and Uninterruptable Power Supplies (UPS).

Key Characteristics

  • Composition: Fe • Si
  • Shapes: Toroid
  • Sizes: 12 mm to 133 mm
  • Permeability: 26µ, 40µ, 60µ
