Discover our range of technologies
We offer a wide range of ferrite cores in terms of materials (i.e. properties) and shapes and sizes. The two major materials classes Mn-Zn and Ni-Zn are sub-divided into materials optimised for power, signal, and EMI shielding applications, or special functionality like shielding - with further material grades designed for certain permeabilities, frequency ranges, and temperature behaviour. Ferrite core parts are pressed from powder cores and sintered, meaning any shape which can be formed with a pressing tool can be designed. Available standard shapes comprise cores suited for bobbin or direct windings, bars, rods, plates, and tiles.
We offer the entire range of combinations of material and shapes, with the option to design customised solutions. Our engineers together with our partners help to find the optimum solution in terms of performance and costs.
Nanocrystalline cores are the perfect solution for EMI shielding applications (common mode chokes CMC), mid-frequency transformers up to about 80kHz, current transformers (CT), and sensors for residual current devices (RCD). Since the first cores were designed about 35 years ago, we are able today to offer a broad variety of different materials and shapes optimised for growing markets: electric transportation including charging, power conversion for renewable energy technologies, railway, and smart meters. Different materials cover the permeability range from 5000 to several 100.000 and saturation induction up to 1,7 T, maintaining low losses allowing for compact designs. Special hysteresis loops (R, Z) are also available. Cores made of thin ribbon, so any shape which can be made from a wound or stacked ribbon is possible to design: toroids, oval or rectangular shapes, also cut into pieces and/or combined to shapes like E-cores, as well as bars.
Our Magnetics Products Technology Centre, which manages our brand Acal BFi kOr, supports you with the selection of the right material, shape, and finishing, and develops customised products quickly and efficiently.
When it comes to developing custom solutions for tomorrow's technologies, we trust our approach to deliver the best possible outcome.
Our engineers will skilfully guide you through each stage of your project, working with you to understand and identify a solution that meets your technical and commercial needs before designing and integrating your solution.
