Magnetic Cores

Three core families — silicon steel wound cores, nanocrystalline cores and ferrite cores — all made to drawing, from samples to production volumes.

Silicon Steel Wound Cores

Grain-oriented silicon steel wound cores for distribution transformers, instrument transformers and reactors. Toroidal, C-core, stepped (JTR) and three-phase 3D formats, cut and annealed in-house to ±0.1 mm.

Nanocrystalline Cores

Iron-based nanocrystalline (1K107) cores for current transformers, residual current devices, smart meters, inverter welders and common-mode chokes. High permeability, low loss, epoxy coated or cased options.

Ferrite Cores

MnZn and NiZn ferrite cores — toroidal rings and EE/EI/ER formats — for switch-mode power supplies, EMI filtering, inductors and high-frequency transformers.
