Overview
The Würth Elektronik 7446222007 is a through-hole current-compensated common mode choke from the WE-LF Type MV series. It features an inductance of 6.8 mH and supports a maximum DC current of 1.5 A per line. The component has a maximum DC resistance of 0.2 Ω. Designed for electromagnetic interference suppression, it utilizes a ferrite core construction suitable for power line filtering applications requiring robust common mode noise reduction.
Feature Summary
- Current-compensated design for balanced power line filtering
- Through-hole mounting configuration for secure PCB integration
- Ferrite core construction for effective high-frequency noise attenuation
Applications
- Power supply input filtering
- Electromagnetic interference suppression in industrial equipment
- Common mode noise reduction in AC/DC conversion stages
Procurement Notes
Verify the specific voltage rating and saturation current characteristics against the official datasheet before finalizing procurement decisions. Ensure that the through-hole footprint dimensions align with the target printed circuit board layout constraints. Confirm compliance with relevant environmental directives such as RoHS requirements for the intended market deployment.
Selection Notes
Select this component when a current-compensated topology is required to maintain magnetic balance in differential signal or power lines. The 6.8 mH inductance value provides significant impedance at common mode frequencies while allowing the rated 1.5 A DC current to pass with minimal resistive loss. Consider the physical size and lead spacing for mechanical assembly compatibility.
Part Context
This part belongs to the WE-LF Type MV series, which focuses on medium voltage applications within the common mode filter category. Wurth Elektronik designs these components to meet stringent EMI standards for global electronic equipment. The series offers various inductance values to suit different filtering requirements across power electronics and industrial control systems.
Replacement Considerations
Direct substitutes must match the 6.8 mH inductance, 1.5 A current rating, and 0.2 Ω resistance specifications. Verify that alternative components share the same through-hole package style and similar frequency response characteristics to ensure functional equivalence without redesigning the PCB layout.
