CM1425-03CP

Overview

The CM1425-03CP is a 4-channel EMI filter array with integrated ESD protection, manufactured by onsemi. It utilizes an RC (Pi) filter topology with component values of 20 pF capacitance and 100 Ω resistance per channel. The device is housed in a CSP package suitable for SMD/SMT termination. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent Pi-filter channels for simultaneous signal line protection
• Provides combined EMI attenuation and electrostatic discharge protection capabilities
• Utilizes compact CSP packaging for space-constrained surface-mount applications

Applications

• Audio headset and speaker line protection
• LCD display interface filtering
• Portable electronic device signal conditioning

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm exact electrical characteristics and pinout configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into manufacturing processes.

Selection Notes

Select this component when four-channel simultaneous filtering is required alongside ESD protection. Ensure the 100 Ω series resistance and 20 pF shunt capacitance align with target impedance matching and cutoff frequency requirements for the specific application lines.

Part Context

This part belongs to onsemi's CM14xx series of EMI filter arrays designed for consumer electronics. These components address the increasing need for signal integrity and device protection in high-density mobile and audio applications where space is limited.

Replacement Considerations

Check for direct substitutes within the CM142x family or other onsemi filter arrays with identical 4-channel Pi-filter configurations and compatible CSP footprints.
