Product highlights
Shop our comprehensive range of soft magnetic cores.

Powder cores
Distributed air gap cores for inductance stability
Since we don’t press with organic binders, our cores resist the thermal aging effects that come with powdered iron cores.

Ferrite cores
Refined MnZn for low losses at high frequencies
Known for high permeability, temperature control and low disaccommodation in a variety of shapes and sizes.

Tape wound cores
The highest permeability — period
Tape, bobbin, nanocrystalline and amorphous cores utilized by defense, aerospace, communications, downhole drilling and more.

Custom cores
Solve what standard cores can’t
Designed to reduce size or cost without compromising efficiency.
Advanced Part Number Finder Tool
Locate the right core by filtering options based on key specifications.
