Product Description
Wurth Elektronik 7446923010 is a 10 mH, 3 A Common Mode Choke from the WE-LF series, featuring a maximum DC resistance of 0.155 Ω and a choke voltage rating of 250V AC. Designed primarily for use in mains filter circuits, this choke utilizes a dual toroidal-core construction with segment winding that provides effective suppression of common-mode interference across a broad frequency range.
This component employs a high-quality core material, which supports efficient suppression in low to medium frequency ranges, and is well-suited for power electronics, switched-mode power supply units, and EMI filters. The choke has a through-hole mount type with 4 pins, offering secure and reliable installation on printed circuit boards.
The Wurth Elektronik choke can operate reliably within a temperature range from -40°C up to 125°C, ensuring durability in diverse industrial, laboratory, commercial, and manufacturing applications. Its packaging in tray and carton facilitates easy handling and protection during transportation and storage.
Typical applications include mains filters to reduce noise and interference in electronic circuits, power electronics for smoothing currents, and switched-mode power supplies for enhanced electromagnetic compatibility.
Inductance of 10 mH promotes effective noise filtering. Maximum DC current up to 3 A accommodates standard current loads. Low maximum DC resistance of 0.155 Ω reduces power losses. Rated for 250V AC operation in typical mains environments.
Through-hole mounting ensures robust PCB connection. Dual toroidal-core design enables broad suppression frequency range. Wide operating temperature range from -40°C to 125°C for industrial use. Packaging designed for protection and ease of use during installation.
