Applications

• High-speed digital signal line filtering
• Power supply noise suppression
• RF circuit interference mitigation

Procurement Notes

Verify the specific impedance tolerance and DC current ratings against the official datasheet before integration. Confirm RoHS compliance status and automotive qualification requirements if applicable to your design. Ensure the selected packaging format matches your automated assembly capabilities.

Selection Notes

Select this component when a 1206 footprint is required for effective EMI reduction in space-constrained designs. The 220 Ohm impedance value targets common switching noise frequencies. Consider the 400 mA current rating to ensure adequate headroom for the target circuit's operational load without saturation.

Part Context

This part belongs to the ABBK series of shielded ferrite beads from Pulse Electronics. The series offers various impedance values and package sizes to address diverse filtering needs. The ABBK variant specifically provides robust shielding to prevent magnetic field leakage, enhancing performance in dense PCB layouts.

Replacement Considerations

Direct substitutes include other 1206 shielded ferrite beads with similar 220 Ohm impedance and 400 mA current ratings. Verify pin compatibility and thermal characteristics before swapping. Cross-reference with manufacturer-specific equivalents that meet the same electrical and mechanical specifications.
