CM1416-03CP

Overview

The CM1416-03CP is an EMI filter array with integrated ESD protection, manufactured by onsemi. It utilizes an RC (Pi) filter circuit topology to suppress electromagnetic interference on data lines. The device features two channels, each incorporating a capacitance of 117 pF and a resistance of 2 Ohms. Designed for surface-mount applications, it is housed in a compact 5-WFBGA or WLCSP package. The component operates within a temperature range of -40°C to +85°C and provides attenuation characteristics suitable for high-frequency noise reduction.

Feature Summary

• Integrates dual-channel RC Pi-filter architecture for effective EMI suppression
• Provides built-in electrostatic discharge (ESD) protection capabilities
• Utilizes low-profile WLCSP packaging for space-constrained designs

Applications

• Data line filtering in portable electronic devices
• EMI suppression for high-speed interface circuits
• Protection stages for consumer audio and video peripherals

Procurement Notes

Verify the specific package variant, as the part may be available in both WFBGA and WLCSP configurations depending on the suffix or manufacturing lot. Confirm current availability status directly with authorized distributors, as supply levels for this component can fluctuate. Ensure that the selected version meets the required thermal and mechanical specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring combined EMI filtering and ESD protection for differential or single-ended data lines. The low resistance value of 2 Ohms minimizes signal integrity impact while maintaining effective noise attenuation. Consider the compact footprint when optimizing board real estate for mobile or handheld devices where space is limited and robust signal protection is critical.

Part Context

This component belongs to the CM1416 series of EMI filter arrays from onsemi. These devices are engineered to address the increasing demand for compact, multi-functional protection solutions in modern electronics. By integrating passive filtering elements with transient protection, the series simplifies bill-of-materials and reduces assembly complexity for designers working with sensitive digital interfaces.

Replacement Considerations

The CM1410-03CP is a documented substitute offering similar functionality with four channels instead of two. Verify channel count requirements and pin compatibility before substitution. Other members of the CM14xx series may serve as alternatives if electrical parameters align with the design specifications.
