CM6407

Overview

The CM6407 is an EMI filter with integrated ESD protection designed for data lines. It utilizes a 3rd-order LC (Pi) low-pass topology to attenuate high-frequency noise while safeguarding sensitive interfaces from electrostatic discharge events. The device features seven independent channels, making it suitable for multi-line applications such as LCD and USB connections. Packaged in a compact 18-bump WFBGA or WLCSP format, it offers a small footprint ideal for space-constrained portable electronics and consumer devices requiring robust signal integrity and component consolidation.

Feature Summary

• Integrates EMI filtering and ESD protection into a single compact package
• Provides seven-channel low-pass filtering for simultaneous data line protection
• Utilizes third-order LC architecture for effective high-frequency noise attenuation

Applications

• LCD interface data line protection
• USB port EMI and ESD suppression
• Portable electronic device signal conditioning

Procurement Notes

Verify the specific package variant (WFBGA vs. WLCSP) and pinout configuration against your PCB layout requirements. Confirm availability status as some sources indicate this part may be obsolete or have limited stock. Ensure the selected component meets the required isolation voltage and capacitance specifications for your target application environment before finalizing procurement.

Selection Notes

Select this component when design constraints require combining EMI filtering and ESD protection to save board space. Evaluate the parasitic capacitance values to ensure they do not degrade signal integrity for high-speed data lines. Consider the thermal performance and soldering profile compatibility of the WLCSP/WFBGA package during the assembly process planning phase.

Part Context

This component belongs to onsemi's portfolio of passive and protection devices aimed at enhancing signal reliability in consumer electronics. It addresses the growing need for compact, multi-functional solutions that reduce bill-of-materials count by integrating filtering and protection functions previously handled by discrete components.

Replacement Considerations

Check for direct substitutes within the same family or comparable 7-channel EMI filters with ESD protection from other manufacturers. Verify that alternative parts match the critical parameters: cutoff frequency, clamping voltage, and package dimensions.
