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.
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.
TDK has expanded its portfolio with new EPCOS pressure transmitters whose performance profiles are specially tailored to the requirements of industry 4.0. These low-profile pressure sensors are characterized by their compact design, high accuracy and excellent long-term stability.
Conventional semiconductors based on silicon are being replaced by wide band-gap (WBG) technologies based on GaN and SiC. These demand a great deal from the passive components – particularly the DC link capacitors. Thanks to its supreme competence in materials and design, TDK offers innovative solutions, enabling the advantages of the new semiconductors.
DK Corporation (TSE:6762) presents the EPCOS Compact S14 AdvanceD-MP series of metal oxide disk varistors that feature smaller dimensions with the same excellent performance as comparable S14 AdvanceD-MP types. The disk diameters of the new B72214P2* varistors range from 13 mm to 14 mm, a reduction of approximately 3 mm.
In conjunction with the increased use of GaN semiconductor, which can operate a high frequency, higher frequencies for switching power supplies have become feasible. Ferrite materials are used in transformer products, but core loss (iron loss) varies greatly depending on the driving frequency, and they are key components in transformer design. This article presents information on the features of PC200 material, which was developed by using GaN, and key points concerning its use.
