TDK introduces various large-size ferrite cores with different shapes for a wide range of industrial applications

TDK Corporation (TSE:6762) presents a variety of new large-size ferrite cores with different core shapes, making this the industry's largest lineup of shapes, sizes, and materials for such large cores*. These are used in a wide range of industrial applications such as motor drives, EV charging stations, various railway/traction applications, power transformers, welding, medical, uninterruptible power supplies (UPS), solar inverters, and other renewable energy applications. These cores allow for optimizing magnetic design for efficiency and thermal performance. 

The new standardized large-size core program contains E, U, I, PM, and PQ cores in the N27, N87, N88, N92, N95, and N97 power materials. Accessories like coil former and mounting hardware are available. 

For simulation, TDK offers the Ferrite Magnetic Design Tool. This is free of charge.
