EMIF06-SD03F3

Overview

The EMIF06-SD03F3 is a 6-line highly integrated low-pass filter designed to suppress EMI and RFI noise for SD card interfaces. It integrates ESD protection diodes on each pin, providing robust defense against transient surge events up to ±18 kV contact discharge as per IEC 61000-4-2 Level 4. The device features ultra-low line capacitance to maintain signal integrity and high data speeds while minimizing PCB space consumption through its compact surface-mount package.

Feature Summary

• Integrates EMI filtering and ESD protection for all SD card pins within a single flow-through package
• Provides enhanced ESD immunity with fast response time and low clamping voltage compliant with IEC 61000-4-2 Level 4
• Maintains high signal integrity via very low line capacitance between lines and ground
• Ensures excellent matching between lines using proprietary solid-state silicon technology

Applications

• Mini and micro Secure Digital memory card interfaces in mobile phones
• Communication systems requiring SD card connectivity
• Portable devices needing compact EMI suppression solutions

Procurement Notes

Verify the specific suffix F3 against official STMicroelectronics documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target SD card interface speed requirements. Check for RoHS compliance status if required by your manufacturing standards. Confirm package dimensions match your PCB footprint design constraints before finalizing procurement.

Selection Notes

Select this component when designing circuits that require simultaneous EMI filtering and ESD protection for SD card slots. It is suitable for applications where board space is limited and signal integrity is critical. Consider the operating temperature range and leakage current specifications relative to your system's power budget and environmental conditions.

Part Context

This part belongs to the EMIF series of integrated filters from STMicroelectronics. It is specifically engineered for secure digital card interfaces, combining passive filtering components with active protection diodes. The series aims to simplify PCB layout by replacing discrete components with a single, highly optimized solution for noise suppression and transient protection.

Replacement Considerations

The EMIF06-mSD01F2 is an obsolete alternative within the same family. Verify functional equivalence regarding line count and protection levels before substitution. No other direct public substitutes are confirmed in the provided documentation.
