Plant in Gravataí

November 18, 2014

60 years of capacitors from Brazil


The plant in Gravataí, Brazil, has been producing capacitors for sixty years. During this period, the plant has developed state-of-the-art technologies for both aluminum electrolytic and film capacitors. As such, it is TDK’s only plant that manufactures both capacitor designs.

Today, more than 90 engineers and technicians here develop robust and reliable products for a wide range of demanding applications in automotive and industrial electronics and for power generation, but also in household appliances and lighting.

The success of Gravataí’s products is driven by their innovativeness and quality. The technological know-how acquired over decades is the basis for technologically superior products to meet the growing demands of the markets.

Altogether, more than 1800 people manufacture capacitors for both the global and local markets, with approximately 70 percent of the sales going to exports. The annual production capacity is more than 1.7 billion units of both aluminum electrolytic and film capacitors.
