The demand for high-speed automotive onboard interfaces is increasing, with a view towards supporting driving safety, reducing the environmental load, and improving comfort. For bidirectional communication, the automotive Ethernet format is commonly used, while LVDS is the choice for one-way communication. With LVDS (Low Voltage Differential Signaling), the preferred approach is to also adopt the PoC (Power over Coax) method that enables transmission of the signal and power supply over a single coaxial cable, thereby reducing the weight of wire harnesses in the car. This page describes usage examples and effects of inductors and chip beads specifically recommended for PoC filter applications.
Surface treatment is indispensable for the secure bonding of plastic parts. Activation with cold plasma is an equally simple yet elegant solution. Relyon Plasma, a subsidiary of TDK Electronics, offers the piezobrush® PZ2 – a handy plasma source based on the TDK CeraPlas™ piezo plasma generator.
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.
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.
Class-D amplifiers, which are used in devices such as smartphones and audio equipment, have the advantages of being compact and highly efficient, but crucially require countermeasures against noise generated by their high-speed switching. TDK has an extensive lineup of products which can provide effective noise countermeasures while ensuring high sound quality and without affecting signals. This article describes the applications and effectiveness of these products in speaker lines for various devices which use Class-D amplifiers.
Industry 4.0 is being shaped by the continuing rise in the degree of automation, by the digitalization that includes the Industrial Internet of Things (IIoT) and by high levels of energy efficiency. In this respect, TDK presents a wide range of innovative EPCOS and TDK key components.
The car of tomorrow is unthinkable without innovative electronics. Correspondingly, there is a vast range of new TDK and EPCOS components, both for conventional vehicle technology and for e-mobility.
From simple gadgets to complex devices for the industrial IoT – they all require compact, reliable and extremely safe power supplies. CeraCharge™, the world’s first rechargeable solid-state SMD battery, is a new technology that meets all these demands.
High-power loads are a major stress factor when fuses and components are switched on, as they cause very high currents to flow. To avoid this, TDK offers ceramic EPCOS inrush current limiters, based on NTC and PTC thermistors – a strong duo when used in combination.
Here are S-parameters where products in the ALT series and common mode filters/chokes are combined in the recommended ways for use with 1000BASE-T.
