What do I really need to focus on doing my design? How do I find the right component for my application? Which technical data is relevant in my case? How do I interpret information from data sheets?
As you might know yourself, there is a lot to look out for in an engineers´ world.
Würth Elektronik offers a wide range of solutions to various areas of the electronic scene to help you designing.
Balunless measurement of mixed-mode scattering parameters
Increasing data volumes, as well as enormous increases in transfer speeds, place high demands on the signal quality. This is especially evident with the current interface USB 3.0, which is also known as SuperSpeed because of its transfer speed of 5 Gbps. While a common mode inductor was adequate for the previous version USB 2.0 with 480 Mbps to guarantee signal quality, special HF components are now needed for noise suppression. How these differ is shown by the Sdd21 measurement.

A practical guide for the selection of power inductors for DC/DC converters.
USB Port Protection
The USB-Interface might be the most distributed PC interface in the world. The usage in industry applications is more and more common. Let’s have a closer look to the special environmental conditions of it.
LinkSwitch-II isolated 4.2 LED driver
Transformer units with 50Hz technology have been used for line input voltage in the lower power range until the late 1990s for cost reasons. Switching offline transformer units have become increasingly competitive through the develpoment of highly integrated switching controllers where the MOSFET is often integrated.
Switched mode power supplies (switching regulators, switch mode power supplies, SMPS) are used to generate a fixed output voltage from a variable input voltage range. Switch mode power supplies are generally far more efficient than linear controllers.
Effective EMI Shielding Concepts
Despite all extensively discussed and recommended design rules for the EMC-conform design of components, the interaction between different functional groups within an apparatus has often a sobering effect when tested in the EMC laboratory. Although installed in a metal casing, the emitted interference radiation is above the threshold.
