WURTH ELEKTRONIK 744233121 Common Mode EMI Filter

The Wurth Electronics WE-CNSW series offers high suppression of common mode EMI noise at high frequencies without affecting data signals. Available in standard and high-frequency (HF) versions, these filters come in various package sizes such as 0603, 0805, 1206, and 1812 for an operating frequency range from 10 MHz to 1 GHz. The HF series uses smaller package sizes like 0504 and 0805, suitable for frequencies from 100 MHz up to 4 GHz. These data line filters provide significant noise suppression at high frequencies while maintaining minimal impact on high-speed signals because of winding symmetry. They are ideal for communication interfaces including IEEE 1394 FireWire, ensuring reliable operation from -40°C to +125°C. Designed for reflow soldering, these filters meet strict thermal and electrical standards, offering excellent durability in demanding electronic applications.
