Overview
The Würth Elektronik 744222 is a WE-SL2 series common mode choke designed for surface mount technology (SMD/SMT) PCB mounting. It features a bifilar winding configuration with an inductance of 1 mH and an impedance of 6 kOhms at 10 kHz. The component supports a maximum DC current of 800 mA and has a maximum DC resistance of 207 mohms. It operates within a temperature range of -40°C to +125°C and meets AEC-Q200 qualification standards. Physical dimensions are 9.2 mm in length, 6 mm in width, and 5 mm in height.
Feature Summary
- Bifilar winding structure for effective common mode noise suppression
- UL compliant housing for safety certification requirements
- Shielded design to minimize electromagnetic interference
- AEC-Q200 qualified for automotive reliability standards
Applications
- Signal line filtering in automotive electronics
- Common mode noise suppression in data communication interfaces
- Power supply input filtering for sensitive circuits
- EMI reduction in industrial control systems
Procurement Notes
Verify the specific suffix or tape/reel packaging option required for your assembly process, as availability may vary between cut tape, reel, or mouseReel formats. Confirm that the AEC-Q200 qualification aligns with your target application's automotive grade requirements. Ensure the 800mA current rating and 207mΩ DCR meet your circuit's thermal and efficiency constraints before finalizing procurement.
Selection Notes
Select this component when a compact SMD common mode filter with bifilar winding is needed for high-frequency noise attenuation. The 1 mH inductance and 6 kOhm impedance provide effective filtering for signal lines. Consider the 800mA current handling capability and low DC resistance for power integrity. The wide operating temperature range suits harsh environments, while the small footprint aids in dense PCB layouts.
Part Context
The 744222 belongs to the WE-SL2 series of common mode chokes from Würth Elektronik. This series is characterized by its shielded construction and suitability for surface mount applications. The components are designed to handle significant common mode currents while maintaining low differential mode inductance, making them ideal for protecting sensitive electronic circuits from electromagnetic interference.
Replacement Considerations
Check for direct substitutes within the WE-SL2 series with similar inductance and current ratings. Verify mechanical compatibility regarding the 9.2mm x 6mm x 5mm footprint and pin configuration. Ensure electrical parameters such as impedance at 10kHz and saturation current match the original design requirements.
