EMIF04-1005M8

Overview

The EMIF04-1005M8 is a four-line low capacitance EMI filter and ESD protection device from STMicroelectronics, designed for mobile device data lines. It utilizes an RC (Pi) second-order low-pass filter topology with integrated ESD protection circuitry. The component operates within a temperature range of -40°C to 85°C and is housed in an 8-UFDFN exposed pad package measuring 1.70mm x 1.50mm x 0.65mm. Key electrical parameters include a channel resistance of 100 Ohms, capacitance of 45pF, and a maximum current rating of 10 mA. It provides high efficiency in EMI filtering, achieving -34 dB attenuation at frequencies between 900 MHz and 1.8 GHz, while complying with IEC 61000-4-2 Level 4 standards for ESD suppression.

Feature Summary

• Integrates EMI/RFI noise suppression with ESD protection in a single monolithic device
• Provides symmetrical low-pass filtering for multiple data lines simultaneously
• Offers high reliability through wafer-level packaging and reduced parasitic elements
• Complies with MIL STD 883G Class 3B standards for enhanced robustness

Applications

• Data lines for mobile devices
• Systems exposed to electromagnetic interference
• High-speed communication ports requiring ESD protection

Procurement Notes

Verify the specific suffix M8 corresponds to the required tape-and-reel configuration and lead-free status. Confirm that the 8-UFDFN exposed pad footprint matches your PCB layout requirements. Ensure compatibility with the specified operating temperature range of -40°C to 85°C for your application environment. Check for any RoHS3 compliance documentation if required by your regional regulations.

Selection Notes

Select this component when designing circuits that require simultaneous EMI filtering and ESD protection for multiple data lines. The 100 Ohm resistance and 45pF capacitance values are suitable for high-speed interfaces where signal integrity must be maintained while attenuating noise above 900 MHz. Consider the small 1.70mm x 1.50mm footprint if space constraints are critical in mobile or compact electronic designs.

Part Context

This part belongs to the EMIF04 series of highly integrated EMI filters from STMicroelectronics. The series is characterized by its ability to suppress electromagnetic interference in systems susceptible to such noise. The EMIF04-1005M8 specifically targets applications requiring robust protection for data lines, combining filtering and protection functions to simplify design and reduce board space consumption compared to discrete solutions.

Replacement Considerations

Direct substitutes within the same family include EMIF04-0410M8 and EMIF04-1502M8. Verify that alternative part numbers match the required number of channels, impedance values, and package dimensions before substitution.
