CM1422-03CP

Overview

The CM1422-03CP is an 8-channel RC (Pi) EMI filter circuit manufactured by onsemi, designed for LCD data line protection. It integrates 100 Ohm resistors and 15 pF capacitors per channel to provide second-order low-pass filtering. The component offers ESD protection and operates within a frequency range of 1 GHz to 3 GHz, delivering 30 dB attenuation. Packaged in a 20-WFBGA WLCSP format with dimensions of approximately 2.05 mm x 1.44 mm x 0.72 mm, it supports surface mount installation across a temperature range of -40°C to +85°C.

Feature Summary

• Provides integrated ESD protection alongside EMI filtering for sensitive data lines
• Utilizes RC Pi-filter topology for effective high-frequency noise suppression
• Compact wafer-level chip scale packaging minimizes board space requirements

Applications

• Mobile device data line protection
• LCD interface circuits
• Portable electronic equipment signal conditioning

Procurement Notes

Verify current availability status as the component is listed as End of Life or scheduled for obsolescence by the manufacturer. Confirm specific package variants such as cut tape or reel options through authorized distributors. Ensure compliance with RoHS standards and check for any regional sales restrictions before finalizing procurement plans.

Selection Notes

Select this component for applications requiring multi-channel EMI filtering with integrated ESD protection in compact form factors. The 100 Ohm resistance and 15 pF capacitance values are optimized for high-speed data lines. Consider the operating temperature range and package dimensions during PCB layout design to ensure proper thermal management and spatial fit.

Part Context

This part belongs to onsemi's family of EMI filter circuits designed for consumer electronics. It addresses the growing need for signal integrity and electrostatic discharge protection in mobile devices. The integration of multiple channels into a single small package helps reduce bill of materials count and simplifies assembly processes for manufacturers.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End of Life status, alternative sourcing should be verified through official onsemi channels or authorized distributors for potential last-time buy opportunities.
