CM1431-06DE

Overview

The CM1431-06DE is a six-channel RC (Pi) EMI filter circuit manufactured by onsemi, designed for LCD and camera applications. It operates within a frequency range of 800 MHz to 6 GHz with a cutoff frequency of 110 MHz. Each channel integrates a 100 Ohm resistor and a 15 pF capacitor, providing 30 dB attenuation. The component features integrated ESD protection and is housed in a compact 12-WFDFN exposed pad package measuring 1.75 mm x 1.4 mm x 0.8 mm. It supports surface mount technology and functions between -40°C and +85°C.

Feature Summary

• Integrates six independent low-pass filter channels for comprehensive signal line protection
• Combines EMI filtering with electrostatic discharge protection capabilities
• Utilizes an RC Pi-network topology for effective high-frequency noise suppression

Applications

• Data lines for mobile devices
• LCD display interfaces
• Camera module signal paths

Procurement Notes

Verify current availability status as the part may be obsolete or discontinued. Confirm package compatibility and pinout alignment during integration. Check for updated datasheets to ensure compliance with current manufacturing standards. Validate thermal performance within the specified operating temperature range. Ensure supply chain stability due to potential lifecycle limitations.

Selection Notes

Select this component when six-channel EMI filtering is required for high-speed data lines. The 100 Ohm resistance value suits typical interface impedances. The 15 pF capacitance provides adequate filtering without excessive signal degradation. Consider the small footprint for space-constrained designs. Verify that the 110 MHz cutoff meets system frequency requirements.

Part Context

This device belongs to the CM1431 series of EMI filter arrays from onsemi. These components are specifically engineered for portable electronics requiring robust signal integrity. The series offers various channel counts to match different interface complexities. They serve as critical passive components in modern mobile and imaging hardware.

Replacement Considerations

Check for direct substitutes within the CM1431 family, such as the CM1431-04DE for four-channel needs. Verify pin-to-pin compatibility before replacing. Consult official obsolescence notices for recommended alternative part numbers.
