Wurth Elektronik 1 mH Common Mode Choke, 3 A IDC, 40 mΩ RDC, Through Hole, WE-LF 7446223001

The Wurth Elektronik 7446223001 is a 1 millihenry Common Mode Choke from the WE-LF series, engineered for effective suppression of common-mode interference in low- to medium-frequency ranges. With a maximum DC current rating of 3 A and a low DC resistance of 40 milliohms, this component delivers reliable electromagnetic compatibility in power and electronic systems.

This component features a dual toroidal-core design with segment windings housed within a 4-pin package to facilitate through-hole mounting and soldering. Its compact size with a length of 23.5 mm, height of 25.5 mm, and depth of 16 mm makes it suitable for space-constrained PCB layouts.

The inductance tolerance of ±30% allows stable performance across temperature variations, supported by an operating temperature range from -25°C to 125°C. This choke meets RoHS standards, reflecting a commitment to environmental compliance and safety.

Applications span mains filtering, power electronics, and switched-mode power supplies where filtering of common-mode noise is critical. Its limited leakage field minimizes interference with adjacent components, optimizing circuit integrity.

High-quality toroidal core material enabling wide frequency range suppression. 4-pin, through-hole solder termination for easy integration on PCBs. Compact dimensions facilitate use in multiple electronic assemblies. Certified RoHS to promote environmental responsibility.

Effective in mains filters, switched-mode power supplies, and power electronic circuits for EMI suppression. Inductance tolerance and thermal range ensure durability across environments.

This Wurth Elektronik choke is an ideal choice for engineers and designers seeking robust, reliable common mode filters in industrial, commercial, and consumer electronics applications.
