CM1481-02DE

Overview

The CM1481-02DE is a two-channel EMI filter featuring an RC Pi network topology. It integrates resistor and capacitor elements to provide low-pass filtering for data lines. The component includes integrated electrostatic discharge (ESD) protection rated at ±8kV according to IEC 61000-4-2 standards. Designed for surface mount applications, it utilizes an 8-WFDFN package with an exposed pad to ensure reliable thermal performance and compact board integration.

Feature Summary

• Integrates dual-channel RC Pi-style filtering networks for effective noise suppression
• Provides robust ±8kV electrostatic discharge protection compliant with IEC 61000-4-2 standards
• Utilizes a compact surface-mount footprint suitable for space-constrained designs

Applications

• I/O port protection for mobile handsets and PDAs
• EMI filtering for data ports in notebook computers
• Signal line protection in cellular phones

Procurement Notes

Verify the specific suffix 'DE' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required 8-WFDFN exposed pad footprint during PCB layout. Cross-reference the datasheet for exact pinout configurations to prevent assembly errors. Confirm that the selected variant meets all necessary regulatory compliance requirements for the target market.

Selection Notes

Select this component when dual-channel signal integrity is required alongside ESD mitigation. The integrated RC Pi structure simplifies design by combining filtering and protection in a single device. Consider the 8-WFDFN package constraints for thermal management and soldering processes. Evaluate the ±8kV rating against the specific environmental ESD risks of the end application to ensure adequate protection margins.

Part Context

This component belongs to onsemi's portfolio of passive and protection devices designed for consumer electronics. It addresses the increasing need for compact, multi-functional solutions in portable devices. The integration of filtering and ESD protection reduces bill-of-materials count and simplifies assembly processes for manufacturers of mobile and computing hardware.

Replacement Considerations

Consult official onsemi substitution guides for verified alternatives. Ensure any replacement maintains the dual-channel configuration and compatible package dimensions. Verify that substitute components meet or exceed the ±8kV ESD protection rating and similar filtering characteristics.
