EMIF04-1502M8

Overview

The EMIF04-1502M8 is a four-line low capacitance EMI filter and ESD protection device manufactured by STMicroelectronics. It utilizes IPAD technology to suppress electromagnetic interference in data lines. The component provides symmetrical low-pass filtering with high efficiency, achieving -34 dB attenuation at frequencies from 900 MHz to 1.8 GHz. It integrates ESD protection compliant with IEC 61000-4-2 Level 4 standards, supporting 15 kV air discharge and 8 kV contact discharge. The device operates within a temperature range of -40°C to +125°C and features a micro QFN package measuring 1.7 mm x 1.5 mm with a maximum height of 0.6 mm.

Feature Summary

• Integrates EMI filtering and ESD protection in a single monolithic device
• Provides symmetrical low-pass filtering for data line noise suppression
• Offers high reliability through wafer-level packaging integration
• Complies with MIL STD 883G Class 3B standards

Applications

• Mobile devices requiring data line protection
• Systems exposed to electromagnetic interference
• Interfaces requiring IEC 61000-4-2 Level 4 compliance

Procurement Notes

Verify the specific suffix M8 to confirm the micro QFN package variant. Confirm current availability status as distribution channels may vary. Ensure compatibility with existing PCB footprint dimensions of 1.7 mm by 1.5 mm during integration planning.

Selection Notes

Select this component when simultaneous EMI suppression and ESD protection are required for multiple data lines. The low capacitance characteristic makes it suitable for high-speed interfaces. Verify that the operating temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the EMIF04 series of integrated filters. It is designed for applications needing compact solutions for signal integrity and electrostatic discharge resilience. The IPAD technology enables significant reduction of parasitic elements compared to discrete components.

Replacement Considerations

Check datasheets for alternative parts offering similar four-line configurations and comparable attenuation characteristics. Ensure substitute components match the physical package dimensions and pinout assignments for direct replacement.
