• Integrated ESD protection for signal line integrity
• Compact surface mount design suitable for space-constrained layouts

Applications

• Data lines in mobile devices
• High-speed digital signal filtering
• EMI reduction in consumer electronics

Procurement Notes

Verify the specific suffix 'DI' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Confirm RoHS3 compliance status directly with the supplier, as environmental declarations may vary by production batch. Ensure the component meets the required thermal operating range for the target application environment.

Selection Notes

Select this component when a compact, low-capacitance solution is required for high-speed data lines. The 9 pF capacitance minimizes signal distortion while the 100 Ohm resistance provides necessary impedance matching. Verify that the 5V voltage rating aligns with the system's operational logic levels before integration into the circuit design.

Part Context

This component belongs to the Alpha & Omega Semiconductor EMI/RFI filter family. It is specifically engineered for suppressing electromagnetic interference on data transmission lines. The Pi-filter configuration offers superior attenuation characteristics compared to single-stage filters, making it suitable for sensitive digital interfaces.
