All product groups are available as standard versions or as customer-specific special solutions — tailored precisely to your application.
Through advanced ceramic manufacturing using manganese-zinc (MnZn) or nickel-zinc (NiZn) ferrites, we produce cores that are optimized for extremely low losses, high permeability and maximum temperature stability. Specially developed for the most demanding high-frequency transformer and inductor applications.
