Magnetics

Electronic components, materials and power supplies to factory automation systems, anechoic chambers, test systems and more.

TDK – Electronic components and Materials

TDK was founded in Japan on 7 December 1935 to manufacture iron-based magnetic material ferrite, which had been recently invented by Yogoro Kato and Takeshi Takei. In 1952 they began production of magnetic tapes, with compact cassette tapes following in 1966; it is for these that the company is most widely noted

TDK Museum

Through videos and practical demonstrations, the museum introduces how TDK’s products and technologies, centered on our strength in ferrite and “magnetism”, have played a role in the evolution of society and how TDK will be involved in the coming future society in an easy-to-understand, enjoyable, and experiential manner.

They develop and manufacture soft magnetic components and materials. These are used in the Products in Power Electronics and RF Communications. A leading world supplier of precision, high permeability magnetic components and materials to the electronics industry.

MAGNETICS – Ferrite and Powder Cores

Product line include powder cores, ferrite cores, and strip wound cores for applications such as chokes, inductors, filters and transformers.

Learn More about Ferrite Cores

Made from MnZn, ferrite cores offer economical solutions for high frequency power transformers and inductors, EMC filters, and other applications.

MAGNETICS - Ferrite Cores - Powder Cores

Ferrites are dense, homogenous ceramic structures made by mixing iron oxide with oxides or carbonates of one or more metals such as zinc, manganese, nickel or magnesium.

Ferrite ETD Cores

ETD cores are an economical choice for transformers or inductors. ETDs offer a round centerpost for minimum winding resistance. Dimensions are optimized for power transformer efficiency. Typical applications of Magnetics ETD cores include differential mode inductors and power transformers.
