EMI7204MUTAG

Overview

The EMI7204MUTAG is a four-channel LC (Pi) low-pass EMI filter with integrated ESD protection, manufactured by onsemi. It features an inductance of 17nH and capacitance of 12pF per channel, supporting data rates up to 125 Mbps. The device operates within a temperature range of -40°C to +85°C and provides a minimum breakdown voltage of 9V. Packaged in an 8-UFDFN exposed pad (1.70mm x 1.35mm), it offers high attenuation of -23dB from 800MHz to 6GHz.

Feature Summary

• Integrates LC (Pi) filtering topology with transient voltage suppression for combined signal integrity and circuit protection.
• Provides robust electrostatic discharge (ESD) protection alongside electromagnetic interference mitigation.
• Supports high-speed data transmission lines with minimal signal distortion.

Applications

• Mobile device data lines
• GPS signal paths
• Bluetooth communication interfaces
• WLAN signal routing

Procurement Notes

Verify the specific ordering suffix (e.g., OST, OSCT, OSDKR) against the required packaging format such as tape and reel or cut tape. Confirm that the 8-UFDFN package dimensions align with the target PCB footprint. Ensure the component meets RoHS3 compliance requirements for the intended market. Cross-reference the datasheet revision date to confirm technical specifications remain current.

Selection Notes

Select this component when simultaneous EMI suppression and ESD protection are required for high-speed digital interfaces. The 4-channel configuration suits multi-line buses like USB or HDMI. Evaluate the 17nH inductance value against the specific data rate requirements to ensure adequate bandwidth without excessive insertion loss. Consider the small form factor for dense board layouts.

Part Context

This part belongs to the EMI720xMU series of complex array filters designed for consumer electronics. It addresses the need for compact solutions that protect sensitive input/output ports from both environmental noise and static discharge events. The integration of filtering and protection reduces the overall component count in mobile and portable devices.

Replacement Considerations

Check for direct substitutes within the EMI720xMU family, such as the EMI7206MUTAG, which shares similar mounting characteristics but may differ in channel count or electrical parameters. Verify pin compatibility and package dimensions before substitution.
