MTL offers authorized wholesale distribution of soft-ferrite, MPP, High Flux, XFlux®, AmoFlux®, Kool Mµ® Powder Cores for the Power conversion industry. MTL is an authorized distributor.

Powder Cores

Magnetics® powder cores are excellent as low loss inductors for switched mode power supplies (SMPS), switching regulators, and noise filters. Molypermalloy Powder cores (MPP), High Flux cores Kool Mµ® cores, and XFLUX® cores are available in a variety of shapes.

Magnetics’ powder cores can be found in a variety of applications including:

  • Power factor correction (PFC)
  • Boost inductors
  • Output inductors
  • Flyback transformers
  • Uninterruptible power supply (UPS) inverters
  • Battery chargers
  • Other high current low ripple applications


Ferrite Cores

Magnetics® Manganese Zinc (MnZn) ferrite cores offer economical solutions for a variety of applications. Magnetics® offers nine materials ranging from 900µ to 10,000µ permeability. Magnetics® ferrites are available in a variety of industry standard sizes and shapes.

Applications include:

  • High frequency power transformers
  • Power inductors
  • Wideband transformers
  • AC-DC Converters
  • Common mode chokes
  • EMC filters
  • Current Sensors
  • DC-DC Converters
  • Common Transformers


Strip Wound Cores

Magnetics® strip wound cores (more commonly referred to as Tape Wound Cores) line includes tape cores, bobbin cores and C and E cut cores made from high permeability thin strip alloys of nickel-iron or grain oriented silicon iron. These alloys are known as Orthonol®, Alloy 48, Square Permalloy 80, Supermalloy and Magnesil® and Supermendur.

Strip wound cores are used in a broad range of applications, including:

  • Current transformers
  • Inductors
  • Magnetic amplifiers (MagAmps)
  • Pulse transformers
  • Output transformers


Iron Powder Cores

Iron powder as a core material has been widely used in RF applications for years. The distributed air gap properties inherent in iron powder cores also make them extremely well-suited for a variety of energy storage inductor applications. Iron powder is a cost-effective design alternative to molypermalloy powder (MPP), high flux, or sendust cores. It can also be used in place of ferrites and iron-alloy laminations requiring a gap.
