Overview
The EMIF02-MIC03M6 is a two-line integrated circuit designed for electromagnetic interference (EMI) suppression and electrostatic discharge (ESD) protection in microphone circuits. It functions as a second-order low-pass RC filter with a resistance of 68 Ohms and capacitance of 45 pF per line. The device operates within a temperature range of -40°C to 85°C and is housed in a compact 6-UFDFN surface-mount package.
Feature Summary
- Integrated EMI/RFI noise suppression for sensitive audio lines
- Built-in electrostatic discharge protection capability
- Compact surface-mount design suitable for mobile devices
Applications
- Data lines for mobile devices
- Microphone input protection circuits
- Systems exposed to electromagnetic interference
Procurement Notes
Verify the specific suffix M6 against official STMicroelectronics documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint, specifically the 6-UFDFN package dimensions. Cross-reference the operating temperature range and filter values with system requirements before finalizing procurement decisions.
Selection Notes
Select this component when designing microphone interfaces requiring combined filtering and protection in a minimal footprint. The integrated RC structure simplifies schematic design by reducing external component count. Verify that the 68 Ohm resistance and 45 pF capacitance align with the desired cutoff frequency and impedance matching for the connected microphone sensor.
Part Context
This part belongs to the EMIF series from STMicroelectronics, which focuses on signal integrity solutions. It is distinct from other variants like the EMIF02-1003M6, which may feature different electrical parameters. The MIC suffix indicates optimization for microphone applications rather than general data lines.
Replacement Considerations
Check for direct substitutes within the EMIF series, such as the EMIF02-1003M6, ensuring pin compatibility and similar filter characteristics. Verify that any alternative maintains the 6-UFDFN package and meets the required -40°C to 85°C operating temperature range.
