Common Mode Chokes Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact electrical characteristics, as variations exist within the DLW31S family. Ensure compatibility with RoHS standards if required by your manufacturing process. Cross-reference the part number with authorized distributors to confirm availability and lead times before finalizing procurement plans.

Common Mode Chokes Selection Notes

Select this component when a 1206 footprint is required for common mode noise suppression on data lines. The 160 Ohm impedance at 100 MHz targets specific high-frequency interference scenarios. Consider the 340 mA current rating to ensure the device does not saturate under normal operating conditions while maintaining low DC resistance for minimal signal loss.

Common Mode Chokes Part Context

This part belongs to the DLW31S series, which focuses on miniaturization and low profile characteristics. The series is designed for applications requiring efficient noise filtering in small form factors. It complements other components in the DLW31 family that offer varying impedance and current ratings for different circuit requirements.

Common Mode Chokes Replacement Considerations

Check for alternative part numbers within the DLW31S series that match the 160 Ohm impedance and 340 mA current specifications. Verify pinout compatibility and physical dimensions before substituting to ensure seamless integration into existing PCB layouts without redesign.
