AOZ8014DI

Overview

The AOZ8014DI is a second-order low-pass RC (Pi) EMI filter manufactured by Alpha & Omega Semiconductor Inc. It integrates four independent filtering channels within an 8-WFDFN package with an exposed pad. Each channel provides a resistance of 100 Ohms and a capacitance of 17 pF, supporting a maximum current of 20 mA. The component operates within a temperature range defined by its surface-mount construction.

Feature Summary

• Integrates four independent signal conditioning channels for multi-line noise suppression
• Utilizes a compact WFDFN package design to minimize board space consumption
• Combines resistive and capacitive elements to form a second-order low-pass filter topology

Applications

• High-speed data line EMI suppression in consumer electronics
• Signal integrity enhancement in portable computing devices
• Noise filtering for peripheral interface connections

Procurement Notes

Verify the specific suffix and tape-and-reel specifications against the manufacturer's latest datasheet before ordering. Confirm that the 100-ohm resistance and 17-pF capacitance values align with the target circuit requirements. Ensure compatibility with the 8-WFDFN footprint during PCB layout validation.

Selection Notes

Select this component when multi-channel EMI filtering is required for signals carrying up to 20 mA. The integrated Pi-filter structure simplifies design compared to discrete components. Evaluate the thermal performance of the exposed pad for adequate heat dissipation in dense layouts.

Part Context

This device belongs to the passive filter category from Alpha & Omega Semiconductor, focusing on electromagnetic interference mitigation rather than active power conversion or switching regulation. It serves as a complementary solution for signal conditioning in high-frequency digital environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical tolerances if considering alternative manufacturers' multi-channel RC filters.
