Core materials

Nanocrystalline cores, Fe-based amorphous and metal powder cores (Fe-Si-Al, Fe-Si, Fe-Ni).

Nanocrystalline cores

Nanocrystalline cores

Very high permeability with low core loss — for EMI suppression and precision measurement.

  • High permeability, low core loss
  • High saturation, stable over temperature
  • Toroid, block and racetrack shapes
Details →
Fe-based amorphous

Fe-based amorphous

High saturation flux with very low iron loss — for transformers and reactors.

  • High Bs, very low iron loss
  • Transformer and reactor cores
  • High power, energy-saving designs
Details →
Metal powder cores

Metal powder cores

Distributed air gap and soft saturation — stable under DC bias.

  • Fe-Si-Al / Fe-Si / Fe-Ni
  • Distributed gap, DC bias stable
  • PFC, energy storage, output chokes

Finished inductors

Common mode chokes, PFC inductors and current transformers, wound and tested in-house.

Common mode chokes

Nanocrystalline cores, broadband EMI suppression for EV, PV and motor drives.

  • Wideband high impedance
  • Compact size at equal performance
  • Custom lead and case options

PFC inductors

Powder or amorphous cores, high DC bias capability with low total loss.

  • Stable inductance under DC bias
  • Low loss at high frequency
  • Designed to your ripple and thermal limits

Current transformers

High accuracy and linearity in a compact nanocrystalline design.

  • High accuracy and linearity
  • Compact, lightweight design
  • Metering, protection and monitoring

Why one source

Samples and small batches welcome.

Core and winding in one plant

We make the core and wind the part, so quality and lead time stay under our control.

Custom design to your datasheet

Send a drawing, a datasheet or a sample — we design to your target.

Short lead time, stable repeatability

In-house tooling and process control keep every batch consistent.

Samples to volume runs

Prototype samples, small batches and volume production all supported.

From strip to finished part

Nanocrystalline, Fe-based amorphous and metal powder cores — and finished inductors built on them.

Strip castingAmorphous and nanocrystalline ribbon cast in-house.
Core formingCutting, winding, annealing and impregnation.
Winding & assemblyCoil winding, assembly and encapsulation.
100% testElectrical test on every part before packing.
