Common Mode Chokes datasheet and documents for DLW21SN121SQ2L
Common Mode Chokes Overview
The DLW21SN121SQ2L is a surface-mount common mode choke from the Murata EMIFIL DLW21S series. It features a wirewound structure in an 0805 (2012 metric) package with dimensions of 2mm x 1.2mm x 1.2mm. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 280 mA. Its maximum DC resistance is specified as 410 mOhms, with an impedance tolerance of ±25%. It operates within a temperature range of -40°C to +85°C.
Common Mode Chokes Feature Summary
- Wirewound construction for stable electromagnetic interference suppression
- Compact 0805 footprint suitable for space-constrained PCB layouts
- RoHS compliant manufacturing process
Common Mode Chokes Applications
- High-speed data line filtering
- USB interface noise suppression

Common Mode Chokes Procurement Notes
Verify the specific suffix SQ2L against official Murata documentation to confirm pin configuration and packaging type. Ensure the procurement channel sources genuine components to avoid counterfeit risks. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to finalizing orders.
Common Mode Chokes Selection Notes
Select this component when a 120 Ohm impedance at 100 MHz is required for common mode noise reduction. Verify that the 280 mA current rating meets the circuit's operational requirements. Consider the 0805 package size for compatibility with existing board footprints and assembly equipment capabilities.
Common Mode Chokes Part Context
This part belongs to the DLW21S series of chip common mode chokes designed for high-frequency applications. The series utilizes wirewound technology to achieve precise impedance characteristics. It is distinct from other DLW variants by its specific impedance value and current handling capabilities within the 0805 form factor.
Common Mode Chokes Replacement Considerations
Check for alternative part numbers within the DLW21S series offering similar impedance and current ratings. Verify mechanical compatibility and electrical performance equivalence before substitution.
