EMI4192MTTAG

Common Mode Chokes Overview

The EMI4192MTTAG is a four-line common mode filter with integrated ESD protection, manufactured by onsemi. It features a 10-WDFN surface-mount package measuring 2.50mm x 2.00mm x 0.80mm. The component provides an impedance of 32 Ohms at 100 MHz and supports a maximum DC current of 100mA with a DCR of 5 Ohms. It operates within a temperature range of -40°C to 85°C and includes TVS diode functionality for electrostatic discharge suppression.

Common Mode Chokes Feature Summary

• Integrates common mode filtering with ESD protection in a single compact surface-mount device
• Provides low resistance signal paths suitable for high-speed digital serial interfaces
• Includes built-in TVS diodes for robust electrostatic discharge suppression

Common Mode Chokes Applications

• High-speed digital serial interface protection
• Common mode noise suppression in data lines
• ESD protection for portable electronic devices

Common Mode Chokes Procurement Notes

Verify the obsolete status and End-of-Life (EOL) notification dated February 22, 2024, before design implementation. Confirm availability through authorized distributors or secondary markets, as standard manufacturing has ceased. Ensure compliance with RoHS3 and REACH requirements if applicable to your supply chain regulations.

Common Mode Chokes Selection Notes

Select this component when space-constrained designs require combined EMI filtering and ESD protection for multi-line interfaces. The 100mA rating limits suitability for high-power applications; verify that the target circuit current remains below this threshold. Consider the 32 Ohm impedance profile against the specific frequency requirements of the protected signals.

Common Mode Chokes Part Context

Part of the EMI41 series from onsemi, designed for integrated noise and surge management. This model specifically addresses the needs of compact electronics requiring multi-channel protection without increasing board footprint significantly compared to discrete solutions.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the EMI41 family or equivalent WDFN-10 packages from other manufacturers. Verify pinout compatibility and electrical parameter equivalence, particularly impedance and current ratings, due to the discontinued status of this specific part number.
