EMIF01-1003M3

Overview

The EMIF01-1003M3 is a single-line EMI filter and ESD protection device from STMicroelectronics. It features an integrated RC configuration with R = 100 Ohms and C = 30 pF, providing -27 dB attenuation at 900 MHz. The component utilizes a Micro QFN (VFQFPN 0.6x1) package with three pins. It operates within a temperature range of -40°C to +85°C and includes built-in ESD protection capabilities for data lines.

Feature Summary

• Integrates EMI filtering and ESD protection in a single compact unit
• Provides high attenuation for RF interference on signal lines
• Utilizes ultra-small footprint packaging for space-constrained designs

Applications

• Data lines for mobile devices
• RF communication equipment I/O ports
• Systems exposed to electromagnetic interference

Procurement Notes

Verify the current lifecycle status as sources indicate this part may be obsolete. Confirm package dimensions and pinout compatibility with existing PCB footprints. Ensure supply chain availability through authorized distributors given potential discontinuation risks.

Selection Notes

Select this component for applications requiring combined EMI suppression and electrostatic discharge protection on single-ended lines. The low capacitance value suits high-speed data interfaces. Consider the small package size for dense board layouts.

Part Context

This device belongs to STMicroelectronics' EMIF series of integrated filters. It is designed specifically for portable electronics where space is limited. The integration of passive components reduces assembly complexity compared to discrete solutions.

Replacement Considerations

Check for direct substitutes within the same family or equivalent RC filter configurations. Verify if newer revisions have replaced this specific suffix. Ensure functional equivalence in attenuation characteristics and package type.
