In electric vehicles (xEVs), thermal management plays a crucial role for battery safety and longevity, inverter and motor monitoring, and comfort also. For this purpose, TDK offers a broad variety of innovative NTC and PTC based temperature sensors solutions, optimized by their design and specification for the respective applications. However, advanced Micronas Hall sensors and motor controllers also perform important tasks, for example in the high-precision control of valves.

The CUR 4000 is a single-axis contactless magnetic-field sensor for galvanically isolated DC and AC current measurements.
This article clearly describes and explains information valuable for our customers related to the features of TDK's CUR 4000 current sensor.

TDK Corporation (TSE: 6762) presents a new range of highly accurate differential pressure sensors (part number B58621V*), designed as printed circuit boards. The sensors are designed for measurement ranges of 16 mbar full-scale (FS), 100 mbar FS and 7 bar FS, with absolute accuracy of up to ±1 percent FS at temperatures from -20 °C to +70 °C.

With the spread of cloud computing and smartphones and the launch of 5G in 2020, the amount of data that moves on the internet is increasing as high-volume video and game data is added to existing documents, images, and sound data.
In addition, technologies are evolving, exemplified by AI, and a digital transformation (DX) is taking place as a result of the use of big data and the internet of things (IoT). To support these advances, however, large numbers of high-performance servers that can process large volumes of data will be needed. In conjunction with the increased performance of processors and various types of ICs, higher clock speeds of power supply ICs on server boards, high current power saving, miniaturization, noise countermeasures in data lines, and surge countermeasures have become urgent issues. Here, we introduce TDK products for addressing and solving these problems including the VLBU series of ferrite power inductors compatible with the high-efficiency needs of VR13 and VR14 applications, the FS series of DC-DC converters with embedded μPOL™, solutions using the ALT series of pulse transformers and ACM series of common mode filters and chokes, and chip varistors and ceramic transient voltage suppressors used for surge protection.

TDK Corporation presents the new B58703M1103A* temperature sensor − specially developed for demanding E-mobility applications, which call for high long-term stability. The NTC sensor is designed for a temperature range of -40°C to +150°C, whereby a temporary load of up to 200°C is permitted. At 25°C the rated resistance is 10 kΩ with a B25/100 value of 3625 K and a tolerance of ±1 percent.

In electric vehicles, temperature monitoring of all power components is a basic requirement for ensuring the safety, reliability and longevity of the entire system. Robust TDK and EPCOS NTC temperature sensors available in a wide range of different designs are key components for this task.

Automobiles are entering a period of change, and technological innovation supporting electrification and its widespread adoption are becoming important topics.
At the same time, measures to reduce CO2 and exhaust emissions by addressing environmental issues require efforts to develop engines with higher efficiency.
In this article, we present TDK temperature sensors (NTC thermistors) and pressure sensor transmitter/pressure sensor die products that are essential for enhancing engine intake and exhaust performance in order to contribute to the resolution of these issues.

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.

The evolution of sensing technology and communication network contribute to the realization of an Autonomous driving society and its growth. Ultrasonic parking assistant is a key sensor for automated driving and parking functions. Ultrasonic parking sensors were in use in Europe long before debate on automated driving became active. TDK has for many years supplied Piezo Disks and ultrasonic driver transformers for use with ultrasonic parking sensors. TDK also developed a multilayer ceramic chip capacitor that exhibits attenuating capacitance (ZL characteristics) under high-temperature environments that is suitable for resonant circuits with Piezo Disk. This article presents Piezo Disk, ultrasonic driver transformers, and MLCC with ZL characteristics.

NTC sensor elements are the functional basis for all kinds of temperature measurements in all major applications. TDK develops and manufactures high accuracy temperature sensors with excellent media resistance and long-term stability for the automotive, industrial, home and heating appliances markets. TDK offers standard portfolio epoxy resin and glass-encapsulated elements for temperature ranges up to 300°C, complimented by NTC chip thermistors.
