Modular Stackable Ferrite U-cores for Flexible Large Designs

TDK Corporation has developed a new kind of ferrite core, the 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. 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. With short lead times, Dexter Magnetic Technologies can provide customers with standard modular cores that allow rapid prototyping.

Moreover, the modular StackPack U-Cores enable further mounting flexibility. "Customers can expand the ferrite with just three parts a corner piece, legs, and spacers," explains Chris Spadafora, Marketing Manager for EPCOS Ferrite Products. "Holes allow an engineer to insert a threaded rod and screw the assembly together. It's an attractive, inexpensive solution."

Chuck Wild, Business Manager at Dexter Magnetic Technologies, agrees: "The new StackPack U-Cores deliver the flexibility to grow designs based on a standard platform. Engineers can increase ferrite height or width whichever way they need to go." Main applications are expected to include high-voltage transformers and high-frequency filter applications.
