EMIF02-MIC03C2

Overview

The EMIF02-MIC03C2 is a second-order low-pass RC (Pi) EMI filter manufactured by STMicroelectronics. It features two channels with a resistance of 68 ohms and capacitance of 100 pF per channel. The device provides -35 dB attenuation at 900 MHz and includes integrated ESD protection. Packaged in a 5-WFBGA/FCBGA surface-mount footprint measuring 1.47mm x 1.07mm x 0.76mm, it operates within a temperature range of -40°C to 85°C. This component is designed for audio applications requiring electromagnetic interference suppression.

Feature Summary

• Integrates dual-channel RC Pi network filtering with inherent ESD protection capabilities
• Provides significant signal attenuation at high frequencies to suppress radio frequency interference
• Utilizes a compact surface-mount package suitable for space-constrained electronic designs

Applications

• Audio circuitry requiring noise suppression
• Systems subjected to electromagnetic interference
• ESD sensitive equipment requiring signal line filtering

Procurement Notes

Verify component availability carefully as this part is listed as obsolete or discontinued by major distributors. Confirm final source documentation for lifecycle status before integration into new designs. Ensure replacement strategies are evaluated due to potential supply chain limitations for this specific STMicroelectronics filter variant.

Selection Notes

Select this component when dual-channel EMI filtering and ESD protection are required in a single small footprint. The 68-ohm resistance and 100-pF capacitance values define the cutoff characteristics. Consider the 5-WFBGA package constraints and thermal operating range during PCB layout and design phase.

Part Context

This device belongs to the EMIF series from STMicroelectronics, specialized for EMI/RFI filtering. It combines passive filtering elements with electrostatic discharge protection mechanisms. The product serves as a solution for maintaining signal integrity in noisy environments while protecting downstream components from voltage spikes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative components must be selected based on matching electrical parameters such as channel count, resistance, capacitance, and package dimensions.
