Telecom transformers

xDSL Digital Subscriber Line transformers The xDSL Digital Subscriber Line transformers (Figure 2.85) are specialized line interface transformers that are designed to optimise the performance of DSL chipsets. With each chipset varying in power drive levels, impedance characteristics and signal spectrum the transformers are very much chipset dependant in their design. Fig. 2.85: DSL Digital Subscriber Line transformers DSL (Digital Subscriber Line) DSL technology...

LAN transformers

LAN transformers

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...

Open Letter to AEC-Q200 Committee on MLCC DC BIAS Ageing Capacitance Loss Issues

Open Letter to AEC-Q200 Committee on MLCC DC BIAS Ageing Capacitance Loss Issues

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...

Tantalum Capacitors Support Nvidia to Shrink AI ‘Supercomputer’ to Credit Card Size

Tantalum Capacitors Support Nvidia to Shrink AI ‘Supercomputer’ to Credit Card Size

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....
