SMD transformers E10 EM series – TDK Electronics Factories Inc.


TDK Corporation presents 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.

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

Description

Measuring just 11.7 x 13.15 x 11.35 mm3, they are extremely compact. The compact design meets clearance and creepage requirements in accordance with 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 component in the new EPCOS transformer series B78307A*A003 is qualified in accordance with AEC-Q200 Rev. D.

Production of electronic components such as transformers and capacitors

TDK Corporation is a subsidiary of TDK Corporation based in Yurihonjo City, Akita Prefecture, Japan, and is engaged in the manufacture and assembly of electronic components. Specifically, the company manufactures ferrite-based magnetic components and other passive components such as transformers and capacitors.

Our Business

TDK is a comprehensive electronic components manufacturer leading the world in magnetic technology.
TDK began its trajectory by producing the world’s first ferrite cores using a magnetic material called ferrite, and the company is now a large manufacturer of components.
Ferrite is a material with many advantageous properties.
Modern TDK commands a wide range of technologies that make daily life more convenient and pleasant. Our products serve a myriad of applications—they provide critical functionality in smartphones, personal computers, electrical appliances, industrial equipment, and automobiles.
TDK components are vital for progress in many areas.
Meanwhile, the power of magnetics continues to inform our global leadership role.

The role played by TDK components —
Unseen enablers of functionality taken for granted.
Many products that surround our daily lives rely extensively on TDK’s wide palette of electronic components. But because these are used internally, they remain mostly unseen by consumers.
If your electronic devices operate as designed and make your day more enjoyable, that means that the components in them are functioning properly.
But without these electronic components, many things that we take for granted these days might never have come about.
