AOZ8175DI

Overview

The AOZ8175DI is a second-order low-pass RC (Pi) EMI filter manufactured by Alpha & Omega Semiconductor Inc. It integrates six independent filtering channels within a single surface-mount package. The component utilizes an RC network configuration with a resistance value of 100 Ohms and a capacitance value of 8 picofarads per channel. Designed for high-frequency noise suppression, the filter features a cutoff frequency of 220 MHz and provides -20 dB attenuation at 1 GHz. It supports a maximum current rating of 20 mA and is housed in a 12-UFDFN exposed pad package.

Feature Summary

• Integrates six independent low-pass filtering channels for multi-line noise suppression
• Utilizes a compact RC Pi-network topology to attenuate high-frequency interference
• Engineered for effective EMI/RFI reduction in sensitive signal lines

Applications

• High-speed data interface noise filtering
• Power line EMI suppression in compact electronics
• Signal integrity protection in mobile devices

Procurement Notes

Verify the specific suffix and tape-and-reel specifications against the manufacturer's latest documentation before ordering. Confirm that the 12-UFDFN exposed pad footprint matches the target PCB layout requirements. Ensure the 20 mA current rating and 100 Ohm resistance values align with the circuit design constraints. Cross-reference the part number with official distributor catalogs to confirm availability status.

Selection Notes

Select this component when multi-channel EMI filtering is required in space-constrained designs. The integrated six-channel architecture reduces board space compared to discrete components. Verify that the 220 MHz cutoff frequency meets the system's noise spectrum requirements. Ensure the operating environment does not exceed the thermal limits associated with the UFDFN package.

Part Context

This component belongs to the passive filter product category from Alpha & Omega Semiconductor Inc. It serves as a specialized solution for electromagnetic interference mitigation in modern electronic systems. The device complements the manufacturer's broader portfolio of power management and signal conditioning components by addressing high-frequency noise issues in compact form factors.
