- Noise reduction on data interfaces such as USB or HDMI
Procurement Notes
Verify the specific suffix code against the manufacturer datasheet to confirm impedance and current ratings. Ensure the ordering part number matches the required 0603 package dimensions and AEC-Q200 certification status. Cross-reference the impedance value at 100 MHz with system requirements before finalizing procurement orders.
Selection Notes
Select this component when space constraints require a 0603 package size while maintaining signal integrity. The 1 A current rating suits moderate power signal lines. Verify that the 22 Ohm impedance at 100 MHz aligns with the target noise spectrum. Consider the low DC resistance to minimize voltage drop across the filtered line.
Part Context
This ferrite bead belongs to the WE-CBF family of SMT components designed for general electronic equipment. The series emphasizes small form factors suitable for modern miniaturized devices. Würth Elektronik manufactures these beads using specialized ferrite materials optimized for broadband noise absorption in compact packages.
