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.

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.

TDK Corporation presents a new series of AC filter capacitors that are UL 810 approved at the component level and carry the CE mark. The capacitors of the B32354S3* series are designed for a rated voltage of 350 V AC and are available with capacitance values of 10 µF to 40 µF.

This article introduces a product overview of MEMS microphone.

As electronic devices become more advanced, the power supply voltage of LSIs used in them is lowered, so their power consumption can be reduced and their speed increased. However, a decrease in the power supply voltage also causes the requirements regarding voltage fluctuations to become more severe, creating a need for high-performance DC-DC converters to fulfill these characteristic requirements, and power inductors are important components that greatly affect their performance. TDK has a widely varied lineup of power inductor products, and this article describes and explains effective methods for using power inductors, and key points for selecting them, according to the required characteristics of DC-DC converters.

TDK Corporation announces that it has reengineered and improved the EPCOS LeaXield™ active leakage current filter, a unique solution that is able to minimize earth leakage currents in converter-based drive systems.

The individual components in variable-speed drives cause earth leakage currents that cumulatively result in the tripping of the RCD. By using the upgraded EPCOS LeaXield™ active leakage current filter, these earth leakage currents be drastically reduced.

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.

If communication waves from cellular or Wi-Fi sources interfere with and intrude into microphone lines for smartphones or other devices, some of their components will become noise components in audible bands known as "TDMA noise", and may be emitted from speakers as unpleasant sound. Countermeasures which implement combinations of TDK's noise suppression filters and ESD Notch Filters can not only demonstrate outstanding effectiveness at suppressing TDMA noise with no effect on signals, but can also provide a variety of other benefits such as improving cellular or Wi-Fi communication reception sensitivity, and providing countermeasures against ESD (electrostatic discharge).

TDK's ANT series ceramic chip antennas feature compact and low profile designs utilizing low temperature co-fired ceramic technology (LTCC). Even with their small size and thin profile, TDK antennas maintain high performance and reliability, all with the industry's smallest "keep-out" area on the PCB which enable ease of PCB design and revision at each development stage.
