CM1431-08DE

Overview

The CM1431-08DE is an eight-channel EMI filter array with integrated ESD protection, designed for high-speed LCD and camera interfaces. It utilizes a pi-style RC topology to provide second-order low-pass filtering. The component integrates four, six, or eight filters within a small surface-mount package. Key electrical parameters include a resistance value of 100 Ohms and a capacitance value of 15 pF per channel. This configuration effectively attenuates electromagnetic interference while safeguarding sensitive data lines against electrostatic discharge events in compact electronic devices.

Feature Summary

• Integrates multiple RC (Pi) filter channels with ESD protection in a single compact package
• Provides second-order low-pass filtering characteristics for signal integrity enhancement
• Designed specifically for protecting high-speed interface lines such as LCD and camera data paths

Applications

• High-speed LCD panel interface protection
• Camera module data line shielding
• Portable device EMI suppression

Procurement Notes

Verify the specific suffix DE against official onsemi documentation to confirm pinout and packaging details. Ensure compatibility with automated assembly processes by confirming tape and reel specifications. Cross-reference the part number with current datasheets to validate that no recent design changes affect functionality or compliance status before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring simultaneous EMI attenuation and ESD protection for multiple high-speed lines. The 100 Ohm resistance and 15 pF capacitance values are suitable for standard high-speed digital interfaces. Consider the physical footprint constraints and the need for integrated protection solutions to simplify board layout and reduce component count in space-sensitive applications.
