EMIF02-MIC07F3

Overview

The EMIF02-MIC07F3 is a highly integrated EMI filter and ESD protection device from STMicroelectronics, designed for audio applications. It features a complex array configuration with six individual chip elements housed in an 8-pin flip-chip BGA package measuring 1.58 x 1.58 mm. The component operates within a temperature range of -30 °C to +85 °C. Key electrical specifications include a maximum reverse standby voltage of 3V, a minimum breakdown voltage of 6V, and a maximum reverse leakage current of 100nA at a test current of 1mA.

Feature Summary

• Integrated suppression of electromagnetic interference (EMI) and radio frequency interference (RFI) noise for sensitive audio circuits
• Built-in electrostatic discharge (ESD) protection capabilities to safeguard microphone inputs
• Compact flip-chip BGA package design optimized for space-constrained mobile and portable devices

Applications

• Microphone line input protection in mobile phones and tablets
• Audio pre-amplifier circuit filtering in consumer electronics
• Accessory detection interface noise suppression

Procurement Notes

Verify the specific suffix F3 against your bill of materials to ensure correct pinout and performance characteristics. Confirm that the 8-WFBGA package dimensions align with your PCB footprint requirements. Ensure compatibility with your assembly process temperatures given the -30 °C to +85 °C operating range. Cross-reference the 3V max reverse standby voltage with your system's audio line levels to prevent signal degradation or component stress during normal operation.

Selection Notes

Select this component when designing audio interfaces requiring combined EMI filtering and ESD protection in a minimal footprint. It is suitable for systems where microphone lines are exposed to potential static discharge events. Consider its low capacitance and specific resistance values if signal integrity is critical. This part is ideal for replacing discrete filter components to save board space and simplify assembly processes in compact handheld devices.

Part Context

This device belongs to STMicroelectronics' EMIF series of integrated filters. It is specifically engineered for audio applications, differing from USB or HDMI variants in its impedance and capacitance profiles. The EMIF02-MIC07F3 integrates passive filtering elements with transient voltage suppression diodes into a single monolithic structure, offering a consolidated solution for noise reduction and port protection in modern electronic equipment.
