Global warming is currently an issue of worldwide concern. CO₂ (carbon dioxide) not only contributes to this problem but also has a significant impact on our health. In the pursuit of improving air quality in various environments, such as homes, offices, and hospitals, there is an escalating demand for sensors capable of detecting CO₂ and various other gases. TDK is developing a CO₂ gas sensor that is significantly smaller in size than previous sensors and consumes less power.

The PLE Series power inductor is a high-efficiency, low-leakage flux, ultra-compact power inductor that excels during operation with small batteries, such as those used in wearable devices.
Using our proprietary structural design and newly developed materials, it achieves a wide range of inductance values through a thin-film process.
This chapter explains the structure and characteristics and provides other useful information including applications.　

We will explain the characteristics of the TDK pattern coil and introduce an example of its use when installed in a wireless charger.
