In e-mobility, the temperature of all system units needs to be constantly monitored. The high currents result in losses with a corresponding generation of heat arising, in particular, at contacts. TDK has now developed a special-purpose high-voltage resistant temperature sensor for connectors.

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.

The evolution of sensing technology and communication network contribute to the realization of Autonomous driving society and its growth. In association with full-scale expansion of the "5G service" next-generation wireless communication standard, great attention is being placed on wireless technology intended for "vehicle-to-vehicle and infrastructure-to-vehicle communication" (V2X) to communicate data between automobiles and their surroundings. While the TDK Group can offer a lineup of various electronic components for V2X, this article introduces a selection of IMU (Inertial Measurement Unit) and high-frequency products for Telematics Control Units (TCUs).

TDK Corporation presents a new series of ceramic-based EPCOS ultrasonic sensor disks, comprising two standard types. The B59050Z0206A030 sensor disk has a diameter of 5.0 mm and thickness of 1.02 mm.

The CUR 423x current sensors feature non-intrusive, galvanically isolated contactless current measurement based on closed-loop TMR technology.
