Piezoelectric powder level sensors provide highly accurate and stable voltage output to indicate the presence or absence of particulate matter referred to as powder. This article describes the driving principle (the piezoelectric unimorph driving principle) and structure of piezoelectric powder level sensors, application in piezoelectric vibration type sensors, and the driving method and driving circuits of piezoelectric unimorphs.

This article introduces a product overview of surface potential sensors.

This article introduces a product overview of toner density/quantity sensors.

This material describes the characteristics of each protection component, as well as the differences between an MLCC and MLV.

This article introduces a product overview of TMR sensors.

TDK has been offering pouch-type EDLCs, and has developed a new ultra-thin EDLC, with a thickness of 0.45mm (max.) that can be stored inside an IC card. It realizes battery-less smart cards equipped with a display, and is suitable for secondary power supplies for wearable devices or IoT devices.

In mobile devices such as smartphones, protection devices such as chip varistors are used to prevent malfunction or damage to the circuit due to electrostatic discharge (ESD), but the noise suppression sheet from TDK known as “Flexield” IFL series is a product which is also effective in suppression of electrostatic discharge. Use case and its effectiveness are presented below.
