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 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.

TDK Corporation has extended its portfolio of PowerHap™ piezo actuators for haptic feedback with the new miniature rectangular 0904H014V060 and 1204H018V060 actuators. They have dimensions of only 9 x 3.75 x 1.4 mm and 12 x 4 x 1.8 mm, respectively.

The innovative PowerHap™ piezo actuator with haptic feedback and integrated sensor functionality is now available in three compact types – 0909H011V060, 1313H018V120 and 2626H023V120 – which can achieve an very high acceleration of 2.5g, 7g and 35g, respectively, under a load of 100 grams.

TDK Corporation is expanding its portfolio of TMR angle sensors with the TAD2140 type in a TO-6 package for automotive and industrial applications. The new sensor provides an innovative system-in-package solution for PCB-less applications

Apart from miniaturization, improved efficiency is the most important development goal in the design of power supply units. And ferrite cores are the decisive factor for efficiency. TDK has developed a new ferrite material and improved geometries for the core designs.
