LAN and LAN RJ45 series Ethernet transformers The LAN Ethernet transformers (Figure 2.82) are not simple transformers, but rather modules in which, depending on the number of ports for which they are suitable, at least two transformers and a certain number of current-compensated chokes are contained. Fig. 2.82: LAN transformers As the name denotes, they are designed as transformers for Ethernet networks. Ethernet is...
Five MLCC manufacturers and Continental Automotive company as user representative discussed the MLCC Class II DC BIAS & Ageing Capacitance Loss as the Hot Panel Topic during the past 2nd PCNS Passive Components Networking Symposium 10-13th September 2019, Bucharest, Romania. The observations and comments have been summarized as an "Open Letter to AEC-Q200" to follow up the topic in wider automotive industry board. Introduction...
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....
by: Tomas Zednicek, EPCI update: 31st October 2019 based on 2nd PCNS Passive Components Networking Symposium 10-13th September 2019, Bucharest, Romania Hot Panel Discussion inputs. 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...
