TDK Presents Compact SMT Transformers for DC/DC Converters

TDK Corporation has introduced the EPCOS E10 EM series, a new range of insulated SMT transformers that are suitable for various DC/DC converter topologies and gate driver circuits in e-mobility and industrial electronics.

TDKThere are four models in the series, with basic winding insulation of a working voltage of 500 VRMS and reinforced insulation of 300 VRMS. The turn’s ratio is between 1:0.76 and 4:1, depending on the model.

Measuring just 11.7 x 13.15 x 11.35 mm3, they are extremely compact. The compact design meets clearance and creepage requirements under the IEC 60664-1 standard (Np/Ns: min. 5.5 mm clearance, min. 6 mm creepage), due to the internal construction of the transformers.

Outstanding reproducibility and reliability are ensured thanks to highly automated production with an AOI final inspection. The components in the new EPCOS transformer series B78307A*A003 is qualified under AEC-Q200 Rev. D.
