Power transformers
EE, EI and ETD geometries for SMPS, LLC and phase-shifted full-bridge designs.
Product line 02 · Ceramic cores
Ferrite Cores
MnZn power ferrites for transformers and chokes, NiZn grades for higher-frequency and EMI work.
MnZn and NiZn power ferrites
Ferrite is chosen at the operating flux swing and frequency, then the geometry follows from the winding window, the gap and the thermal path.
- Grade: MnZn for power conversion, NiZn for higher frequency and EMI suppression. Each grade is characterised over a stated frequency and temperature window.
- Loss: quoted at your flux density and frequency.
- Gap and insulation: gap length and any requirement on creepage or clearance are stated on the part drawing.
Scope of the range
| Material systems | MnZn / NiZn | Grades as listed in the material data |
|---|---|---|
| Shapes | E, EE, EI, ETD, EER, PQ, RM, toroid | Custom geometries on request |
| Air gap | Per drawing | Gap length stated per part number |
| Accessories | Bobbins and hardware on request | Availability confirmed per order |
Shape families
Chokes and PFC
Gapped geometries for boost PFC chokes and DC-link chokes; gap chosen from the bias current.
EMI and high frequency
NiZn grades and toroids for common-mode chokes and high-frequency work.
Custom cores
Non-standard stacks, grinding and tooling evaluated from a drawing before quoting.
