EMI8142MUTAG

Common Mode Chokes Overview

The EMI8142MUTAG is a common mode filter with integrated electrostatic discharge (ESD) protection designed for high-speed data lines. It features four data lines within an XDFN-10 package. The device supports a maximum current of 100 mA and offers a typical DC resistance of 6 ohms. It provides robust protection against contact discharge up to 15 kV. The component operates reliably within a temperature range of -40°C to +85°C, ensuring signal integrity in demanding environments.

Common Mode Chokes Feature Summary

• Integrates common mode filtering with ESD suppression for combined noise reduction and transient protection
• Supports differential signaling I/Os requiring simultaneous interference mitigation and static discharge defense
• Utilizes a compact XDFN-10 surface mount package for space-constrained PCB layouts

Common Mode Chokes Applications

• High-speed serial data interface protection
• Differential signaling line conditioning
• Portable electronic device input/output ports

Common Mode Chokes Procurement Notes

Verify the specific datasheet version for the EMI8142MUTAG to confirm electrical characteristics and mechanical dimensions. Ensure compatibility with the target application's voltage levels and signal speeds. Check for any recent product change notifications that might affect pinout or performance specifications before finalizing the design.

Common Mode Chokes Selection Notes

Select this component when both EMI filtering and ESD protection are required on the same line to save board space. The integrated solution simplifies design compared to discrete components. Consider the 6-ohm resistance value for its impact on signal attenuation at the intended operating frequency.

Common Mode Chokes Part Context

This part belongs to the EMI814x series from onsemi, which focuses on protecting high-speed interfaces. It complements other ESD devices like the EMI8042MUTAG by offering integrated filtering capabilities rather than standalone protection.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the EMI814x family. Verify pin-to-pin compatibility if replacing with similar common mode filters from other manufacturers.
