by Tomas Zednicek, EPCI Last month I was presenting at T.I.C. 60th annual assembly in Hong Kong tantalum capacitors and its future. This morning two web articles grab my attention that fit nicely as pieces of the puzzle to complete the picture. NVIDIA today introduced Jetson Xavier™ NX, the world’s smallest, most powerful AI supercomputer for robotic and embedded computing devices at the edge....

This article can be downloaded in pdf version here. MLCC capacitors are dominating today's capacitor market enabling high grade of electronics miniaturization. The continuous downsizing and use of higher and higher dielectric constant materials for MLCC class II capacitors...
As illustrated with the transformer equivalent circuit, transformers have numerous parasitic properties, which can have a negative effect on the signal. In this chapter it is therefore explained why and where one applies transformers. An additional section deals with the requirements for signal transformers. To conclude the chapter, some standard commercially available transformers are described. 3.1 Function and application areas of transformers As a...
SMD NiZn Ferrite Core Storage Choke SMD storage chokes with highly dynamic and low loss NiZn ferrite cores (such as Würth Elektronik WE-PD series) are suitable as chokes in switching control applications up to a clock frequency of approx. 10MHz and offer high current loading capacity and low DC resistances. There are a multitude of construction types available for the different types of application:...
2.3 Power Inductors and Calculations Switched-mode power supplies are becoming ever more widespread. The semiconductor manufacturers have made their contribution, offering a wide range these integrated circuits with simplified circuit design. Care must be taken in the selection of the appropriate storage choke to fully utilize the advantages of switching regulators. The selection of cores and windings of storage chokes are optimized for use...
