Wurth Elektronik Surface Mount Common Mode Line Filter WE-CNSW 1812 Ferrite Core 11μH Dual Inductor 450mA 744235110

Wurth Elektronik 744235110 surface mount common mode line filter features an 11μH dual ferrite core inductor suitable for suppression of electromagnetic interference in electronic circuits. This unshielded component comes in an 1812 package size, designed for surface mounting onto printed circuit boards (PCBs).

The filter supports a maximum DC current of 450mA and withstands operating temperatures ranging from -40°C minimum up to 125°C maximum. It is RoHS compliant and meets the automotive industry standard AEC-Q200, making it reliable for automotive and industrial applications.

With a maximum DC resistance of 800mΩ and inductance tolerance between -30% and +50%, this common mode choke provides effective noise suppression in high speed data line interfaces such as USB 2.0, Firewire, LVDS, and LAN connections. The 4-pin dual inductor construction ensures good winding symmetry to minimize signal interference.

Physical dimensions measure 4.5mm in length, 2.8mm in height, and 3.2mm in depth, suited for high-density PCB designs requiring surface mount technology (SMT) components. The core is ferrite material which offers excellent magnetic properties for noise attenuation.

Installation is recommended via reflow soldering process. This part is not molded and is classified as unshielded, so PCB layout should consider EMI shielding requirements.

This filter is an essential component for industrial electronics, automotive electronics, telecommunications, and data transfer equipment where EMI suppression is critical to system performance and compliance with electromagnetic compatibility (EMC) regulations.
