Compact transformers in E10 EM series are for DC/DC converters

Insulated surface mount transformers in the Epcos E10 EM series by TDK are suitable for various DC/DC converter topologies and gate driver circuits in e-mobility and industrial electronics.

There are four models in the series, with basic winding insulation of a working voltage of 500Vrms and reinforced insulation of 300Vrms. The turns ratio is between 1:0.76 and 4:1, depending on the model.

The transformers measure 11.7 x 13.15 x 11.35mm3. The compact design meets clearance and creepage requirements in accordance with the IEC 60664-1 standard (i.e. Np/Ns: minimum 5.5mm clearance, minimum 6.0mm creepage).

The automated production process ensures reproducibility and reliability, says TDK, with a final automated optical inspection. The transformers are qualified in accordance with AEC-Q200 Rev. D.

TDK was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products. Its portfolio features passive components such as ceramic, aluminium electrolytic and film capacitors, as well as magnetics, high frequency, and piezo and protection devices. The portfolio also includes sensors and sensor systems such as temperature and pressure, magnetic, and MEMS sensors. In addition, TDK provides power supplies and energy devices and magnetic heads.

Products are marketed under the brands TDK, Epcos, InvenSense, Micronas, Tronics and TDK-Lambda.

TDK focuses on demanding markets in automotive, industrial and consumer electronics, and information and communication technology.

The company has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America.
