With the new standards for ferrite cores with distributed air gaps, TDK offers an opportunity for downsizing and increasing power density.
In addition, distributed gapped cores (DG cores) allow the possibility to optimize the design of magnetics in terms of efficiency and thermal performance. The internal construction of TDK’s DG cores has a rated temperature of up to 180 °C.
The new standardized DG core program contains E, ETD, and PQ cores in our power materials N87, N95 and N97 and covers an inductance factor range between 60 nH and 400 nH.
All DG cores can be used with our broad portfolio of accessories like coil formers and mounting hardware.
Our ferrite cores with distributed air gaps are used in a wide range of automotive and industrial applications such as EV charging stations, on-board chargers and DC-DC converters, solar inverters, UPS, industrial SMPS as well as telecom and server SMPS.
