LAN transformers come in gigabit versions
The WE-LAN AQ series of LAN transformers are manufactured by full automation and come in a new gigabit package that exhibits outstanding electrical properties and compact design. With WE-LAN AQ, the previous wound toroid cores are replaced with SMD-solderable transformers and common-mode choke elements. The low return loss attenuation gives the package an outstanding signal […]
Power-supply noise, Part 2: What is differential mode noise?
Part 1 looked at the basics of noise, especially concerning power supplies. There are two noise sources which are not as obvious to many engineers as noise that results from the switching action of the power supply: differential mode noise and common-mode noise. These two noise modes have different causes and thus different solutions Q: […]
Power-supply noise, Part 1
“Noise”—perhaps nothing worries design engineers as much as the implications of this single five-letter word. There are good reasons for this worry. Noise is often unpredictable; may come from internal and somewhat controllable sources, or external impossible-to-control sources; it can affect performance accuracy and consistency; it can cause products to not meet their target design […]
