XFlux® Ultra Cores

For High Power and Efficiency


XFlux® Ultra cores offer the same high saturation found in standard silicon-iron XFlux while providing a 20% improvement in core loss. Applications include high efficiency uninterruptible power supplies (UPS), high power SMPS, and power factor correction (PFC) for on-board chargers (OBC).

Key Characteristics

  • Composition: Fe • Si
  • Shapes: Toroid, E, EQ, LP, Block, Cylinder, EER, U
  • Sizes: 13.5 mm to 134 mm
  • Permeability: 26µ, 60µ
  • Coating Color: Brown
