Plant in Heidenheim
December 21, 2017
70 years of inductors and capacitors made in Germany
Heidenheim is one of TDK's longest-standing facilities. Today, some 430 employees produce inductors and power capacitors at the 29,000 m² facility, of which approximately three quarters are shipped to customers in the automotive industry.
More than two thirds of the electronic components manufactured here are for the European market.
Over the years the focus of the plant has evolved from pure manufacturing to development, process design and logistics in order to support the company's global business. About 30 percent of the employees are now employed in these areas. Production processes and automation concepts developed in Heidenheim are used in all other plants for inductors and capacitors.
Growing percentage of sales with products for e-mobility
Among the components manufactured here are innovative PCC power capacitors for hybrid and electric vehicles. These components are built into the power supply units for electric motors, where they stabilize voltage, store energy and thus play a part in facilitating better vehicle acceleration. The share of products made in Heidenheim for cutting-edge e mobility applications currently stands at about 15 percent and is growing all the time.
Miniaturized data line chokes account for by far the largest number of units produced here. These inductors enable interference-free data exchange between in-vehicle electronic controllers. They are increasingly also being used in driver assistance systems and in both telematics and autonomous driving applications.
Investment in cutting-edge production concepts
Further process automation with cutting-edge machines and Industry 4.0 concepts are being employed for the production of power capacitors. For example, the plant is currently working on the installation of a fully automated production line with several robots.
