The Würth Elektronik 744220203 is a shielded common mode choke from the WE-SL2 series, designed for signal line applications. It features an inductance of 20 mH and an impedance of 50 kOhms at a test frequency of 10 kHz. The component supports a maximum DC current of 200 mA with a maximum DC resistance of 2.6 Ohms. It operates within a temperature range of -40°C to +125°C and meets AEC-Q200 automotive qualification standards. The physical dimensions are 9.2 mm in length, 6 mm in width, and 5.3 mm in height.
Verify the specific order code against the manufacturer's official datasheet to ensure correct impedance and tolerance specifications. Confirm that the surface mount package dimensions align with your PCB footprint requirements. Check for any recent product change notifications regarding material composition or manufacturing location updates before finalizing procurement plans.
Select this component when high impedance at 10 kHz is required for common mode noise attenuation in sensitive signal lines. Ensure the circuit current does not exceed the 200 mA rating to prevent saturation. Consider the 2.6 Ohm DC resistance impact on signal integrity and power loss in low-voltage applications. Verify thermal management capabilities given the 125°C maximum operating temperature limit.
This part belongs to the WE-SL2 series of common mode chokes from Würth Elektronik. The series offers various inductance values tailored for different frequency ranges. The 744220203 specifically targets applications requiring robust noise suppression in compact spaces, leveraging its shielded design and automotive-grade reliability certification.
Consult the manufacturer's cross-reference guide for verified substitutes. Ensure replacement parts match the 20 mH inductance, 50 kOhm impedance, and 200 mA current rating. Verify compatible package dimensions and terminal configurations for direct PCB integration without redesign.
