Basic Concept

Contribute to the world through technology is the contribution to the society by TDK’s business. Toward this end, we are focusing on innovative technology development in our priority markets of automotive, ICT, and industrial & energy, helping to save, store, and reuse energy and solve other pressing issues that modern society is facing. Furthermore, the pursuit of zero-defect product quality based on superior technological competence and realized through a unified production process that extends from the raw materials to the final product will continue unchanged in the future. Providing high quality products and services is our way of striving for the advancement of society.


To realize a happy future society, TDK aims to achieve the six goals of SDGs through its technology and products: Good Health and Well-Being for All (SDG 3), Affordable and Clean Energy (SDG 7), Industry, Innovation, and Infrastructure (SDG 9), Sustainable Cities and Communities (SDG 11), Responsible Consumption and Production (SDG 12), and Climate Action (SDG 13).
These SDGs represent areas in which we feel we can provide maximize the potential and value of TDK technology and products to solve social issues facing us today. In our efforts to draw an ideal society where issues are successfully solved, TDK will develop its technology and products, we aim to realize a happy future society.

TDK Electronics challenges the SDGs throughout the value chain

TDK Electronics takes its responsibility toward society and the environment very seriously. At our facilities around the world, we are constantly working on projects to further improve our energy efficiency and consume even fewer resources. At the same time, we are cultivating employees' awareness that our behavior and our technologies and solutions can play a part in meeting the social, economic and ecological goals of the global community. The United Nations’ Sustainable Development Goals (SDGs) serve as guideposts along this path.

Our products are used mostly in automotive and industrial electronics, but also in household appliances and entertainment electronics, smartphones, wearables and medical technology. Our components help make vehicles cleaner, safer and more comfortable. We also supply key components for photovoltaic installations and wind turbines, for example, as well as for other renewable energy applications and low-loss HVDC transmission over long distances. Many of our components and solutions are instrumental in reducing energy consumption in our customers' applications. And we are careful to choose and deploy materials that minimize the burden on the environment. Additionally, we are working hard to further reduce weights and volumes in order to realize savings on both production and transportation. We are thus contributing to six SDG goals on which TDK places special emphasis: SDG 3: Good health and well-being; SDG 7: Affordable and clean energy; SDG 9: Industry, innovation and infrastructure; SDG 11: Sustainable cities and communities; SDG 12: Responsible consumption and production; and SDG 13: Climate action.

Special NTC thermistors to measure temperatures in heated car seats are one example. The manufacture of these products is now completely lead-free: No lead is used in the ceramic, metallization as well as in the solder alloy that forms the mechanical and electric link between the metallized NTC ceramics and the connecting wires. This alloy has a much lower melting point than leaded alloys, so lowering the solder bath temperature by about 100 degrees to 250 °C saves large amounts of energy at the production facility in Batam, Indonesia.

Another example is the new PowerHap 15 G, a piezo actuator* based on multilayer-piezoceramic plates that deliver excellent haptic feedback. It is ideal for use in touchscreens and others in vehicles, smartphones and tablets. This innovative component boasts unrivaled performance, as well as reducing per-click power consumption from 130 to just 8 millijoules. Its weight and volume have also been reduced substantially. During application, the new PowerHap requires about 90 percent less energy than conventional solutions.

  • Piezo actuator use piezoelectric material that generate electrical voltage in response to applied mechanical stress.

In production and administration too, TDK Electronics is contributing to achievement of the SDGs. For example, more and more TDK Electronics factories now use electricity from renewable sources. All plants in Germany plus those in Austria, Brazil, Iceland and Hungary and our contract manufacturer in Croatia have all already switched to green electricity. As a whole, TDK Electronics already derives more than two thirds of the electrical power it consumes from renewable sources, and this proportion will increase as growing numbers of plants likewise move over to green electricity. We are also running projects such as the one in India, where our Nashik plant now operates a photovoltaic installation covering nearly 11,000 square meters. The Nashik facility thus aims to reduce its CO2 emissions by roughly 1,100 tons a year, as well as saving money on energy. As a result, production at the plant will be both less expensive and kinder to the environment.

InvenSense is actively engaged in solving social and environmental issues by using its unique sensor technology. The key technology at InvenSense is the integration of sensors for transducing physical phenomena with electronics to capture and digitize sensor signals. The close coupling of these technologies enables small, low power, low cost, smart sensors that are easily integrated into a myriad of devices. Our software team codes complex algorithms to take advantage of our sensor performance and sensing integration to inspire customers to deploy new applications and experiences.
A society with a deep sensor infrastructure will enable more automation of menial tasks besides environmental or chemical monitoring, and thereby leave more meaningful jobs for humans. It will also improve efficiency, leading to a better balance between work and life for people. InvenSense sensor technology has the full range of possibilities, such as managing mental health and well-being through activity sensing and tracking, and improving safety by enabling autonomous vehicles. In the trend of social transformation by digital transformation (DX), smart sensors that analyze collected data and accumulate knowledge are essential. InvenSense technology and products are thus contributing to six Sustainable Development Goals on which TDK places special emphasis: SDG 3: Good health and well-being; SDG 7: Affordable and clean energy; SDG 9: Industry, innovation and infrastructure; SDG 11: Sustainable cities and communities; SDG 12: Responsible consumption and production; and SDG 13: Climate action.

As an example that is already in development as a prototype, the InvenSense sensor is included in a device that is attached to surfboards to measure ocean chemistry and temperatures during regular surfing sessions. Utilizing the information provided by the device will make it possible to address climate change issues.

Another example is streetlights being enabled by sensors as part of a smart infrastructure deployment. Currently streetlights are on continuously during the nighttime. A smart streetlight, with a motion or presence sensor could dim with no one around and brighten when someone is present. The transformation to digital street lighting will greatly reduce the overall energy usage. Eventually, combining sensors with machine learning will accelerate the trend of DX.

InvenSense seeks to contribute to solving social issues at an even higher level by reducing the energy consumption, cost, and size of products. In order to achieve it, we need to review all of our manufacturing processes as well as the lifecycle of our products, extend the product lifetimes, and improve the recyclability.
Since the role that companies play in society and the environment has been drawing increasing attention in recent years, it is essential to achieve both business growth and social sustainability. This must be kept in mind when formulating a business plan. As a leading technology company, we make the world safer, healthier and more fun for current customers but especially for future generations.
