Applications
- High-speed data line noise suppression
- USB interface EMI filtering
- HDMI signal integrity protection
Procurement Notes
Verify the exact part number suffix to ensure correct impedance and current ratings. Confirm RoHS compliance status if required for specific regulatory environments. Check datasheet revisions for any updates to mechanical dimensions or thermal characteristics before finalizing procurement specifications.
Selection Notes
Select this component when space constraints require a 2x1.2mm footprint. Ensure the operating current does not exceed 400mA to prevent saturation. Verify that the 90 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Consider thermal management requirements based on the DCR value during continuous operation.
Part Context
This component belongs to the WCM series of common mode chokes from TAI-TECH. The series offers various impedance values and current ratings within standardized surface mount packages. The 2012 size indicates the physical dimensions, providing a balance between performance and board space efficiency for consumer electronics applications.
Replacement Considerations
Cross-reference with other 2012 package common mode chokes offering similar 90 Ohm impedance and 400mA current ratings. Verify pin compatibility and inductance curves to ensure equivalent noise suppression performance without modifying the PCB layout.
