CM1401-03CP

Overview

The CM1401-03CP is a 4-channel EMI filter array with integrated ESD protection, manufactured by onsemi. It utilizes an RC (Pi) filter topology to suppress electromagnetic interference while safeguarding sensitive components from electrostatic discharge events. The device features four filtering channels and four dedicated ESD protection channels within a single compact package. Designed for surface-mount assembly, it operates reliably across a temperature range of -40°C to +85°C. The component is housed in a 15-WFBGA (CSP-15) package, offering a small footprint suitable for space-constrained mobile and portable electronic applications.

• Speaker protection circuits

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as HST may exist within the product family. Confirm current availability status directly with authorized distributors or the manufacturer, as supply levels can fluctuate. Ensure the selected part matches the required package type and channel configuration for your specific design implementation.

Selection Notes

Select this component when simultaneous EMI attenuation and ESD robustness are required on multiple signal lines within a limited board area. The integrated RC Pi-filter structure simplifies design compared to discrete solutions. Consider the operating temperature range and package dimensions to ensure compatibility with the target application's thermal and spatial constraints.

Part Context

This component belongs to onsemi's CM14xx series of EMI filter arrays. These devices are engineered to provide comprehensive signal line protection in compact form factors. The series typically includes variants with different channel counts and filter characteristics to address diverse interface requirements in modern electronic systems.

Replacement Considerations

Check for direct substitutes within the CM14xx family, such as the CM1401-03CP-HST, which shares similar functional attributes. Verify pinout compatibility and electrical specifications before substituting any alternative part numbers.
