CM1457-06CP

Overview

The CM1457-06CP is a Praetorian III EMI filter array with integrated ESD protection, manufactured by onsemi. It utilizes an inductor-based L-C architecture within a Chip Scale Package (CSP) featuring a 0.40mm pitch. The device integrates four, six, or eight filter channels, each implemented with a specific component value of 6pF-35nH–4.7pF-35nH–1.8pF. It provides greater than -35dB attenuation over the 800MHz to 2.7GHz frequency range and supports data rates up to 160Mbps.

Feature Summary

• Integrates multiple EMI filtering channels with ESD protection in a compact CSP form factor
• Provides ±15kV ESD protection at external pins compliant with IEC 61000-4-2 contact discharge standards
• Features OptiGuard coating for improved reliability during assembly processes

Applications

• LCD and camera data lines in mobile handsets
• I/O port protection for mobile handsets, notebook computers, and PDAs
• EMI filtering for data ports in cell phones and notebook computers

Procurement Notes

Verify the current lifecycle status before procurement, as public sources indicate this part may be planned for obsolescence. Confirm package availability and ensure compatibility with existing PCB layouts requiring 0.40mm pitch CSP components. Cross-reference datasheet revisions to guarantee parameter consistency with design requirements.

Selection Notes

Select this component for applications requiring high-density EMI suppression and robust ESD protection in portable electronics. The low parasitic inductance of the CSP design makes it suitable for high-speed data lines. Ensure the operating environment aligns with the specified temperature range and that the attenuation characteristics meet the specific noise profile of the target interface.
