CM1460-08DE

Overview

The CM1460-08DE is an EMI/RFI filter circuit manufactured by onsemi, designed for surface-mount applications in a TDFN-8 package. It functions as an LC (Pi) network with third-order low-pass characteristics. Key electrical parameters include an inductance of 17 nH and capacitance of 15 pF per channel. The device provides electrostatic discharge (ESD) protection and operates within a frequency range of 800 MHz to 3 GHz. It supports up to eight channels and maintains a compact form factor with dimensions of 2 mm x 2 mm x 0.8 mm.

Feature Summary

• Integrates LC Pi-filter topology for effective high-frequency noise suppression
• Provides integrated electrostatic discharge protection capabilities
• Supports multi-channel configurations for parallel signal line filtering

Applications

• High-speed data interface protection
• Portable electronic device signal conditioning
• Consumer electronics EMI mitigation

Procurement Notes

Verify the specific suffix DE against official onsemi documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through current datasheets. Ensure design-in compatibility with target PCB footprint requirements before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring simultaneous EMI filtering and ESD protection for multiple high-speed lines. The TDFN-8 package offers a small footprint suitable for space-constrained layouts. Evaluate the 17 nH inductance value against system impedance matching requirements to ensure optimal signal integrity performance.

Part Context

This component belongs to the CM1460 series of EMI filter arrays from onsemi. These devices are engineered to address electromagnetic interference challenges in modern digital systems. The series utilizes advanced semiconductor processes to combine passive filtering elements with active protection structures in a single integrated package.

Replacement Considerations

Check for updated revisions within the CM1460 series. Verify pinout compatibility if considering alternative manufacturers. Confirm that substitute components meet the same 17 nH inductance and 15 pF capacitance specifications.
