CM1631-08DE

Overview

The CM1631-08DE is an LCD and Camera EMI Filter Array with integrated ESD protection, manufactured by onsemi. It features a pi-style RC filter topology integrating four, six, or eight filters in a small form factor. The component utilizes a uDFN-16 package with dimensions of 3.4 mm x 1.45 mm x 0.55 mm. Key electrical parameters include a capacitance of 15 pF, resistance of 100 Ohm, and attenuation of 35 dB within the frequency range of 1 GHz to 3 GHz. It operates between -40°C and +85°C.

Feature Summary

• Integrates pi-style RC filter arrays with ESD protection for signal lines
• Provides high attenuation performance across wide frequency bands
• Designed for ultra-thin footprint requirements in portable devices

Applications

• LCD display interface protection
• Camera module signal filtering
• Portable electronic device EMI suppression

Procurement Notes

Verify the specific datasheet revision and exact channel count configuration (four, six, or eight) prior to ordering, as the CM1631 family encompasses multiple variants. Confirm that the uDFN-16 package dimensions align with the target PCB layout constraints. Ensure compatibility with the required operating temperature range of -40°C to +85°C for the intended application environment.

Selection Notes

Select this component when space-constrained designs require combined EMI filtering and ESD protection for high-speed data lines. The low capacitance value helps preserve signal integrity while attenuating noise. Consider the specific channel count variant needed for the number of protected lines in the system design.
