- Effective suppression of high-frequency common mode noise
Applications
- USB 2.0 interfaces in PCs and peripheral devices
- LVDS lines in laptops and LCDs
Procurement Notes
Verify the specific suffix (e.g., U vs C) against official datasheets, as variations may indicate differences in packaging or minor electrical tolerances. Confirm the manufacturer is Shenzhen Sunlord Electronics Co., Ltd. Ensure the part number matches the exact impedance and current ratings required for the circuit design before ordering.
Selection Notes
Select this component when space constraints require a low-profile form factor. Ensure the application involves differential signal lines requiring common mode noise filtering at frequencies around 100MHz. Verify that the operating current does not exceed the 280mA rating to maintain performance and reliability.
Part Context
This component belongs to the SDCW series of common mode chokes from Sunlord. These components are designed for compact electronic devices where board space is limited. The series offers various impedance options to suit different noise levels and signal frequencies.
Replacement Considerations
Check for direct substitutes with identical 90Ω @ 100MHz impedance and 280mA current rating. Ensure replacement parts match the 2x1.2mm package dimensions and pin configuration. Verify thermal and voltage ratings align with the original specifications.
