Common Mode Chokes Procurement Notes

Verify the complete part number including suffixes against official Murata documentation to ensure correct impedance, tolerance, and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure supply chain sources provide authentic components matching the manufacturer's datasheet parameters.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring 2.2 kOhm common mode impedance at 100 MHz with a 200 mA current rating. The 1206 package size suits space-constrained layouts. Verify that the 1.2 Ohm DC resistance aligns with power loss constraints and that the 85°C operating temperature meets environmental requirements.

Common Mode Chokes Part Context

This component belongs to the DLW31S series of wire-wound chip common mode chokes manufactured by Murata Electronics. The series utilizes proprietary ceramic and wire technologies to achieve high impedance in small footprints. These components are designed for general electronic applications where effective noise suppression is required without significant signal degradation.

Common Mode Chokes Replacement Considerations

Cross-reference with other DLW31SN variants having identical 2.2 kOhm impedance and 200 mA ratings. Verify pin compatibility and physical dimensions before substitution. Consult Murata engineering for alternative part numbers if specific electrical tolerances or thermal characteristics differ.
