EMIF02-1003M6

Overview

The EMIF02-1003M6 is a two-line highly integrated device designed to suppress electromagnetic interference (EMI) and radio frequency interference (RFI). It functions as a dual-line symmetrical low-pass filter with integrated ESD protection. The component utilizes a second-order RC Pi-type design featuring R=100 Ohms and C=30pF per line. It operates within an ambient temperature range of -40°C to 85°C and provides attenuation of -25dB at 900MHz.

Feature Summary

• Dual-line symmetrical low-pass filter architecture for data lines
• Integrated electrostatic discharge (ESD) protection capabilities
• Second-order RC Pi-type circuit design for effective noise suppression

Applications

• Data lines for mobile devices
• Systems exposed to electromagnetic interference
• High-speed signal transmission paths requiring noise filtering

Procurement Notes

Verify the specific suffix M6 corresponds to the required tape and reel packaging configuration when ordering. Confirm that the QFN-6L package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the RoHS compliance status with current regulatory standards for the destination market.

Selection Notes

Select this component when both EMI suppression and ESD protection are required in a single compact package. The integrated nature reduces board space compared to discrete solutions. Consider the 100 Ohm resistance and 30pF capacitance values to ensure signal integrity is maintained for the specific data rate applications. Verify compatibility with the voltage levels present on the protected lines.

Part Context

This part belongs to STMicroelectronics' EMIF series of EMI filters. These components are engineered for portable electronics where space constraints are critical. The integration of filtering and protection functions simplifies the bill of materials and assembly process for manufacturers designing compact consumer electronic devices.

Replacement Considerations

Check for direct substitutes within the same family, such as other EMIF02 variants with different pin counts or electrical characteristics. Ensure any replacement maintains the QFN-6L package outline and identical functional specifications for seamless integration.
