CM1690-04DE

Overview

The CM1690-04DE is a pi-style EMI filter array with integrated ESD protection, manufactured by onsemi. It integrates four C-L-C filters within a compact WDFN-8 package measuring 2 mm x 2 mm x 0.8 mm. Key electrical parameters include a capacitance of 15 pF, inductance of 17 nH, and a cutoff frequency of 350 MHz. The device provides 30 dB attenuation across the 800 MHz to 2.7 GHz frequency range. It operates between -40°C and +85°C and utilizes SMD/SMT termination.

Feature Summary

• Integrates four LC (Pi) filter channels with ESD protection in a single component
• Provides high attenuation for electromagnetic interference suppression
• Designed for low-profile surface-mount applications

Applications

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

Procurement Notes

Verify current availability status as the CM1460-04DE variant is listed as obsolete; confirm lead times and end-of-life notifications directly with onsemi or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component for designs requiring integrated EMI filtering and ESD protection for multiple lines in space-constrained environments. Ensure the 15 pF capacitance and 17 nH inductance values align with target signal integrity requirements.

Part Context

This part belongs to the CM1690 family of pi-style EMI filter arrays. It serves as a specialized solution for protecting sensitive interfaces against both electromagnetic interference and electrostatic discharge events in portable electronic devices.

Replacement Considerations

Check for direct pin-compatible substitutes within the CM1690 series or equivalent LC filter arrays from other manufacturers that meet the 15 pF / 17 nH specification.
