Welcome at to Coil Winding 2015! The Coil Winding, Insulation and Electrical Manufacturing Exhibition (CWIEME) in Berlin is the world’s leading exhibition for these technologies. We are presenting the comprehensive portfolio of EPCOS and TDK ferrite cores and accessories as well as high-performance TDK ferrite and rare-earth magnets for all electronics sectors. We’re looking forward to your visit!

Product highlights

Low losses at high frequencies

The new EPCOS N59 ferrite material is characterized by low losses at high frequencies. It was developed specifically for power supplies and frequency converters that operate with fast-switching power semiconductors on a GaN basis. The new material is optimized for a frequency range from 700 kHz to 2 MHz. Its maximum transmissible power is reached at a switching frequency of 2 MHz and an operating temperature of 100 °C. The ferrite material’s Curie temperature is in excess of 250 °C.

The N59 ferrite material is particularly suitable for transformers based on ring core or planar topologies. The outstanding properties of this material will enable considerably more compact power supplies to be designed in future. At the same time, its efficiency is improved due to the low losses of the ferrite material, which is why the use of N59 contributes to significantly greater energy savings. The current version can only be used without DC magnetic bias.

Modular U-cores for flexible large designs

The new EPCOS stackable U-cores feature a unique modular ferrite design that offers flexibility and economy for high-voltage transformer and HF filter applications. The new U-cores are tooled by and available exclusively from Dexter Magnetic Technologies as Dexter StackPack™ U-Cores. US-based Dexter Magnetic Technologies is a provider of optimized magnetic solutions and distributor of TDK and EPCOS products.

The new modular EPCOS stackable U-cores provide standard options that can fit any application. This is a major advantage in applications that require large ferrite cores but are limited by manufacturing constraints and high tooling costs. As a result, designers have been cutting and gluing large U and I cores together to make them bigger – an approach that is not only imprecise but also expensive. The standardized design of the StackPack U-Cores, which were developed together with Dexter Magnetic Technologies, enables multiple configurations as well as lower costs than custom tooling or machining.
