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.

TDK Corporation (TSE:6762) presents new series of extremely compact TVS diodes with parameters matched to the various ports of the USB-C port as well as other high-speed interfaces. TVS diodes with very low parasitic capacitance values and low clamping voltage are required especially for the high-speed ports (Tx / Rx) of USB-C, which operate at up to 40 Gbit/s with USB4 version 1. The B74111U0033M060 and B74121U0033M060 types are suitable for this purpose, with very low capacitance values of 0.48 pF and 0.65 pF at 1 MHz, respectively, which means that signal integrity is not compromised. The clamping voltages are only 3.8 V or 3.9 V with an ITLP of 8 A. The protection devices are designed for ESD discharge voltages of up to 15 kV. These TVS diodes are manufactured in the extremely compact WLCSP 01005 and WLCSP 0201 packages and are extremely flat with heights of 100 µm and 150 µm respectively. This means that the TVS diodes can also be integrated into USB-C SIP modules.

This is an electric double-layer capacitor with a metal foil laminate film (EDLC/supercapacitors).Low-resistance electric double-layer capacitors (EDLC/supercapacitors) are effective as capacitors for providing supplementary power during peak output, backup during power supply loss, energy harvesting, or regenerative energy storage. They are thin and lightweight, which makes them appealing for use in mobile products.

The number of smartphones and other mobile devices that are compatible with NFC (Near Field Communication) is increasing. Thanks to the adoption of a newly-developed low-loss ferrite material, TDK’s MLJ series multilayer ferrite coils now offer improved communication properties which are ideal for NFC-equipped devices, while featuring compact package sizes.

PiezoListen is the world's first piezoelectric type speaker that supports a wide range. Thanks to a world leading thinness of 0.49 mm, it can fit almost anywhere. The product causes the object to which it is glued to vibrate and thereby become a speaker. Because the entire surface vibrates, the sound has wide directivity, and uniform sound can be enjoyed at any location. You can also listen to music from Piezo Listen ™ piezo speakers.

The high precision of piezoresistive sensors and their ability to measure absolute, gauge and differential pressure allow their versatile use in a wide range of applications.
For industrial equipment and machineries the information provided by the pressure sensors can be used to operate hydraulic or pneumatic equipment in the most effective way but furthermore connect to the new Industry 4.0 standards.
The increasing requirements in automotive for fuel efficiency and reduction of harmful emission demand for long-term stable and highly accurate sensors. Besides the media resistance, some of the application require the pressure sensors to be freeze resistant but most important the sensors need to provide a reliable signal over lifetime.
All applications place increasingly demanding requirements on the distinctive characteristics of the pressure dies and call for specific design features already on the die level. The TDK pressure sensors portfolio has been developed with a strong focus on increased sensitivity and high performance with a smaller die size. In addition, particular attention is paid to specific features for media resistance and easy process ability.

Chip varistors and TVS diodes are commonly used as over-voltage protection components.
Their structural design and manufacturing methods are completely different, but they offer similar characteristics with regard to protection from static electricity.
They generally can therefore be used interchangeably in a circuit, but there are cases where chip varistors are considered to be not suitable.
For historical reasons, many of the specification items given in catalogs and data sheets are different, which makes it difficult to compare characteristics based solely on these data, unlike in the case of capacitors and other general components.
The aim of this article is to clarify the difference between varistors and diodes and to introduce data that can be used to compare the two.

TDK Corporation presents two evaluation kits that provide an initial impression of the varied possibilities of haptic feedback that can be realized with PowerHap™ piezo actuators.

The TDK ICP-101xx Barometric Pressure Sensorfamily is based on MEMS capacitive technology which provides ultra-low noise at the lowest power, enabling industry leading relative accuracy, sensor throughput, and temperature stability.

Motion- and gesture-based devices from InvenSense are rapidly becoming a key function in many consumer electronic devices, including mobile, wearable, Smart Home, and automotive and industrial devices. Our motion solutions, including gyroscopes, accelerometers, compasses, and pressure sensors, detect and track an object's motion in three-dimensional space, allowing consumers to interact with their electronic devices by tracking motion in free space and delivering these motions as input commands. InvenSense devices across the board have industry leading relative accuracy, sensor throughput, and temperature stability.
