Common Mode Chokes datasheet and documents for DLW21SN670HQ2L
Common Mode Chokes Overview
The DLW21SN670HQ2L is a wirewound common mode choke from the Murata EMIFIL DLW21S series, housed in an unshielded 0805 (2012 metric) surface-mount package. It exhibits an impedance of 67 Ohms with a ±25% tolerance at a test frequency of 100 MHz. The component supports a maximum DC current of 320 mA and maintains a maximum DC resistance of 310 mOhms. It operates within a temperature range of -40°C to +85°C.
Common Mode Chokes Feature Summary
- Wirewound construction for effective common mode noise suppression
- Unshielded design suitable for standard PCB layouts
- Compact 0805 footprint for space-constrained applications
Common Mode Chokes Applications
- Signal line filtering in portable electronic devices
- Noise suppression for high-speed data interfaces
- EMI reduction in consumer electronics power circuits
Common Mode Chokes Procurement Notes
Verify the specific suffix HQ2L against official Murata documentation to confirm packaging type and tape dimensions. Ensure the impedance value matches the target circuit requirements at the operating frequency. Confirm RoHS compliance status through the manufacturer's latest certification records before finalizing procurement orders.
Common Mode Chokes Selection Notes
Select this component when a low-profile, unshielded common mode choke is required for 0805 footprints. The 67 Ohm impedance at 100 MHz suits moderate noise frequencies. Verify that the 320 mA current rating exceeds the application's peak DC load to prevent saturation. Consider thermal derating if ambient temperatures approach the upper limit.
Common Mode Chokes Part Context
This part belongs to the DLW21S series of miniature common mode chokes designed for high-frequency noise suppression. The series utilizes wirewound technology to provide stable performance across varying environmental conditions. It is intended for use in compact electronic systems where size constraints are critical.
Common Mode Chokes Replacement Considerations
Consult Murata's official cross-reference tools for verified substitutes. Ensure any replacement maintains the 0805 footprint, similar impedance characteristics, and compatible current ratings without altering the board layout.
