Common Mode Chokes Procurement Notes

Verify the specific suffix SQ2L against official Murata documentation to confirm package dimensions and termination specifications. Ensure the procurement source provides valid traceability records. Confirm that the delivered components match the specified electrical parameters and physical characteristics defined in the manufacturer datasheet before integration into production lines.

Common Mode Chokes Selection Notes

Select this component when space constraints require a 0805 footprint for common mode filtering. It is suitable for applications requiring 180 Ω impedance at 100 MHz with a 330 mA current rating. Consider the unshielded nature of the device and its operating temperature limits when designing for harsh environments or high-power circuits.

Common Mode Chokes Part Context

This part belongs to the DLW21S series of wirewound common mode chokes. The series is characterized by small size and low profile, designed for high-density PCB layouts. It utilizes Murata's proprietary ceramic and wire technology to achieve stable performance across various digital communication interfaces.

Common Mode Chokes Replacement Considerations

Cross-reference with other DLW21S variants having identical impedance and current ratings. Verify pin compatibility and thermal characteristics before substituting with alternative manufacturers' offerings.
