- Power line filtering
Procurement Notes
Verify the specific ordering suffix to ensure the correct packaging format (Reel, Cut Tape, or MouseReel) matches your assembly requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the datasheet version to ensure all electrical parameters align with your design specifications.
Selection Notes
Select this component when designing circuits requiring 300 mA current handling with significant common mode noise attenuation. The 2 kOhm impedance at 20 MHz makes it suitable for higher frequency interference suppression. Ensure the PCB footprint accommodates the 6.5 mm x 3.6 mm SMD package dimensions.
Part Context
This part belongs to the WE-SL1 series of SMD common mode line filters from Würth Elektronik. The series is engineered for compact electronic designs where space constraints require surface-mount solutions without compromising noise filtering performance.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
