CM1451-08CP

Overview

The CM1451-08CP is an inductor-capacitor (L-C) based EMI filter array with integrated electrostatic discharge (ESD) protection, housed in a CSP package. It functions as a 5th order low-pass LC Pi filter with 8 channels. Key electrical parameters include a total inductance of 34nH and a total capacitance of 28.5pF. The device supports a current rating of 30 mA and utilizes a 20-WFBGA package. It operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates EMI filtering and ESD protection in a single compact component
• Utilizes LC Pi topology for effective noise suppression
• Designed specifically for data line protection in mobile devices

Applications

• Data lines for mobile devices
• LCD interface protection
• Camera module signal lines

Procurement Notes

Verify the specific suffix CP indicates the WFBGA package configuration. Confirm RoHS3 compliance status if required by your manufacturing standards. Check moisture sensitivity level classification, which is listed as Level 1, ensuring no special handling restrictions apply during assembly. Ensure the supplier provides official datasheets from California Micro Devices or authorized distributors to validate part authenticity.

Selection Notes

Select this component when simultaneous EMI attenuation and ESD protection are required for high-speed data lines. The 8-channel configuration suits multi-lane interfaces such as LCD or camera connections. Consider the 30 mA current rating and 34nH inductance values to ensure compatibility with the target signal integrity requirements and power constraints of the application circuit.

Part Context

This part belongs to the CM1451 series of EMI filter arrays. It is manufactured by California Micro Devices Corp. The series includes variants like the CM1451-06, differing primarily in channel count and pin configuration. These components are designed to replace discrete filter and protection circuits, saving board space in portable electronics.

Replacement Considerations

Check for direct substitutes within the CM1451 family, such as the CM1451-06CS, noting differences in channel count and package type. Verify that any alternative maintains the same L-C topology and ESD protection capabilities to ensure functional equivalence without redesigning the PCB layout.
