Wurth Elektronik Surface Mount Common Mode Line Filter with Ferrite Core 22 μH Dual 1812 WE-CNSW 744235220

Wurth Elektronik model 744235220 is a Surface Mount Common Mode Line Filter designed for high frequency EMI noise suppression in sensitive electronic applications. This device features a dual inductor construction with a ferrite core, offering an inductance value of 22 μH. Encapsulated in an industry-standard 1812 package, the filter measures 4.5 mm in length, 3.2 mm in depth, and 2.8 mm in height, suitable for compact PCB layouts.

The component supports a maximum DC current of 250 mA and operates reliably within a wide temperature range from -40°C to 125°C. It complies with the AEC-Q200 automotive standard, making it suitable for automotive and industrial applications where quality and durability are critical. Its maximum DC resistance of 2.65 Ω ensures efficient current handling with minimal power loss.

The inductance tolerance ranges from -30% to +50%, offering flexibility depending on circuit requirements. The unshielded design focuses on common mode noise suppression without affecting differential mode signals.

Packaging in tape and reel format facilitates automated placement and soldering processes in mass production. The surface mount termination style is compatible with reflow soldering techniques, ensuring reliable connection to PCB pads.

The filter's RoHS compliance confirms it meets environmental safety standards, aligning with global electronic manufacturing regulations.

Typical applications include USB 2.0 interfaces, Firewire connections, LVDS transmission lines, LAN circuits, and other high-speed data communication systems where common mode EMI noise suppression is necessary for signal integrity.
