About us

A magnetic core partner that answers with data

We work from your drawing and operating conditions, then return a material recommendation with measured values. Production, testing and export packing are handled in one flow, so specification changes do not have to travel between suppliers.

Ferrite, amorphous and nanocrystalline cores from a single source

Custom shapes, air gaps, coatings, cases and bobbin assemblies

Lot-level magnetic and dimensional test data with every shipment

English-speaking sales and engineering support for European buyers
