TDK at a Glance for Investors | Products at Work



The wave of digital transformation (DX) is surging across various areas of the ICT society. As a result of the proliferation of 5G communications and the Internet of Things (IoT), the amount of information circulated on a daily basis is growing explosively. In response to these developments, traditional cloud computing, which processes information in bulk at data centers, is shifting to edge computing, where distributed processing is performed at a location close to the user’s terminal. TDK’s highly varied and extensive lineup of electronic components and devices support the new network society.
