HKR GmbH Elektrotechnischer Gerätebau

Since 1985 HKR has been supplying the world of power electronics with high-quality chokes, powder cores and sinusoidal filters. Our products can be found almost everywhere where materials with extraordinary magnetic and electrical properties are required - from drive technology to wind energy parks and solar fields to mining locomotives. We have a wide range of standard cores at our disposal, but we are also happy to create special shapes tailored to your individual requirements. The chokes are all manufactured to your specifications. The secret of our Swabian success story and the basis of all inductive components is the HaKRon® powder composite material we developed ourselves - one of many innovations that our development engineers research every day.
