How Extremely High Speed Data Line Chokes Filter High Frequency Noise

Würth Elektronik Webinar

With the increase in switching speeds in digital circuits like USB 3.1/3.2, the common-mode noise is being generated at higher and higher frequencies. This noise can interfere with 4G/LTE or Wi-Fi/ Bluetooth antennas resulting in “Antenna de-sense” and communication failure.

In this webinar, we present and explain an innovative common mode choke based in the transmission lines principle as the best solution to filter that high-frequency noise issue. At the same time, we explain the main differences of this new technology with the current one in our portfolio, the ferrite core-based common mode chokes.

This new technology will be a game-changer for your designs!

The webinar will include the below topics:

• Introduction to modern-day noise coming from new interfaces
• Noise filtering mechanisms
• Conventional common mode choke technology
• New & evolutionary ceramic common mode choke concept
• Comparison & conclusion
