Common Mode Chokes Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status prior to integration. Check for end-of-life notifications as this specific part number may be discontinued. Ensure storage conditions meet moisture sensitivity level requirements. Validate pin compatibility with existing board footprints before procurement.

Common Mode Chokes Selection Notes

Select this component when space constraints require a 4x4mm form factor with low profile. Choose based on the required 850 Ohm impedance at 100 MHz for noise suppression. Ensure the circuit current does not exceed 1.9A to maintain performance. Consider thermal management within the -40°C to +105°C operating range. Verify that the DCR value meets voltage drop requirements in the power path.

Common Mode Chokes Part Context

This component belongs to the DLW44 series of EMIFIL common mode chokes. It is part of Murata's portfolio of passive filters designed for electromagnetic interference suppression. The series offers various impedance and current ratings within a standardized small outline package.
