CM1409-08DE

Overview

The CM1409-08DE is an 8-channel EMI filter circuit manufactured by onsemi, designed for high-speed data line protection. It integrates RC (Pi) filter networks with ESD protection capabilities within a compact TDFN-8 package measuring 2 mm x 2 mm x 0.8 mm. The device features a cutoff frequency of 210 MHz and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a capacitance of 7.5 pF and resistance of 240 Ohms per channel, providing 25 dB attenuation in the 800 MHz to 3 GHz frequency range.

Feature Summary

• Integrates eight independent channels for simultaneous signal conditioning
• Combines low-pass filtering with electrostatic discharge protection
• Utilizes a compact surface-mount design for space-constrained layouts

Applications

• High-speed LCD interface protection
• Camera module signal line filtering
• Mobile device data bus EMI suppression

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official Material Composition Declarations. Check current lifecycle status as availability may vary. Ensure packaging specifications match production requirements before finalizing orders.

Selection Notes

Select this component when designing circuits requiring integrated EMI filtering and ESD protection for multiple high-speed lines. The 8-channel configuration reduces board space compared to discrete solutions. Verify that the 240 Ohm resistance and 7.5 pF capacitance values align with target signal integrity requirements and impedance matching needs.
