B66375 & B66894 Distributed Gapped (DG) Cores

TDK B66375 and B66894 Distributed Gapped (DG) Ferrite Cores feature N87, N88, N95, or N97 core material and assist with downsizing and increasing power density in applications. These E cores with distributed air gaps help optimize the design of magnetics in terms of efficiency and thermal performance. The B66375 series provides an 80nH to 150nH inductance factor range (AL value) and +155°C maximum operating temperature. The B66894 series consists of a coil former and core with an inductance factor range (AL value) of 80nH to 100nH. TDK B66375 and B66894 DG Ferrite Cores are used in a wide range of automotive and industrial applications, including electric vehicle (EV) charging stations, onboard chargers (OBC) and DC-DC converters, solar inverters, uninterruptible power supplies (UPS), industrial switch-mode power supplies (SMPS), and telecom and server SMPS.
