AOZ8045DI

Overview

The AOZ8045DI is an integrated RC Pi filter manufactured by Alpha & Omega Semiconductor Inc. It is designed for surface-mount applications to suppress electromagnetic interference. The component features a resistance value of 100 Ohms and a capacitance value of 9 picofarads. It utilizes a compact SMD package with dimensions of 2.50mm in length and 1.20mm in width, suitable for space-constrained electronic designs.

Feature Summary

• Integrates RC Pi filtering topology for effective noise suppression
• Compact surface-mount design for high-density PCB layouts
• Optimized for EMI/RFI reduction in sensitive circuits

Applications

• Power supply input filtering
• Battery charger signal conditioning
• Portable device noise mitigation

Procurement Notes

Verify the specific manufacturer datasheet for absolute maximum ratings and thermal characteristics before integration. Confirm that the 100 Ohm resistance and 9 pF capacitance values align with the target circuit's impedance requirements. Ensure the surface-mount footprint matches the PCB land pattern exactly to prevent assembly defects.

Selection Notes

Select this component when a low-profile solution is required for high-frequency noise attenuation. The integrated nature reduces component count compared to discrete RC networks. Consider the physical dimensions of 2.50mm x 1.20mm for strict spatial constraints in portable or miniaturized electronics where standard through-hole filters are too large.

Part Context

This part belongs to the EMI/RFI filter category within Alpha & Omega Semiconductor's portfolio. It serves as a passive component solution for signal integrity management. The device complements active power management ICs by providing clean power rails or quiet signal paths in mixed-signal environments.

Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Verify compatibility with existing board layouts if considering alternative manufacturers.
