CM1692-04DE

Overview

The onsemi CM1692-04DE is a four-channel LC (Pi) EMI filter array designed for data line protection in mobile devices. It integrates low-inductance inductors and capacitors to suppress electromagnetic interference while providing electrostatic discharge (ESD) protection. The component utilizes a compact UFDFN-8-EP surface-mount package, enabling efficient space utilization on printed circuit boards. Key electrical characteristics include an inductance of 17 nH per channel and a capacitance of 11.8 pF per channel, ensuring minimal signal distortion for high-speed interfaces.

Feature Summary

• Integrates four independent LC filter channels within a single compact package
• Provides combined EMI suppression and ESD protection capabilities
• Designed specifically for high-speed data line filtering applications

Applications

• Mobile device data line filtering
• High-speed interface protection
• EMI suppression in portable electronics

Procurement Notes

Verify the specific suffix '04DE' corresponds to the 4-channel configuration with tape and reel packaging. Confirm the UFDFN-8-EP package dimensions match your PCB footprint requirements. Ensure compatibility with your assembly process regarding lead-free specifications. Cross-reference the datasheet for exact inductance and capacitance tolerances required by your design.

Selection Notes

Select this component when a multi-channel solution is required for data lines requiring both EMI filtering and ESD protection. The 17 nH inductance and 11.8 pF capacitance values are optimized for high-speed signals. Consider the small UFDFN-8-EP footprint if board space is limited. Verify that the integrated ESD protection levels meet the standards of your target application environment.

Part Context

This part belongs to the CM1692 family of EMI/RFI filters from onsemi. These components are engineered for mobile and portable electronic applications where space constraints and signal integrity are critical. The family includes various channel configurations to suit different interface requirements.

Replacement Considerations

Check for equivalent parts such as the CM1692-08DE if additional channels are needed. Verify pinout compatibility before substituting with other manufacturers' EMI filter arrays. Ensure the replacement maintains the same 17 nH / 11.8 pF electrical characteristics.
