EZA-CT21AAAJ

Overview

The Panasonic EZA-CT21AAAJ is a surface-mount RC network featuring four channels within an 0805 (1608 metric) package. It integrates capacitors of 22pF with a tolerance range of -20% to +30% and resistors of 47Ω with ±5% tolerance. The device operates at a maximum DC voltage of 12V. Physical dimensions are 1.6mm in length, 0.8mm in width, and 0.6mm in height.

Feature Summary

• Integrates four independent RC filter channels into a single compact surface-mount component
• Provides low-pass filtering characteristics for signal conditioning
• Designed to replace discrete components, reducing printed circuit board footprint

Applications

• Data line protection in mobile devices
• Signal processing circuits requiring stable operation
• Networking applications involving system-on-chip interfaces

Procurement Notes

Verify the specific capacitance value against project requirements, as external sources indicate potential variations between 22pF and 47pF for this series. Confirm the operating voltage rating matches the circuit design, noting discrepancies between 12V and 25V specifications found in different listings. Ensure the package size corresponds to the PCB layout constraints.

Selection Notes

Select this component when space optimization is critical for multi-channel filtering. The integrated design simplifies assembly compared to using individual discrete resistors and capacitors. Consider the specific tolerance requirements for both resistance and capacitance to ensure signal integrity in high-speed data lines.

Part Context

This part belongs to the Panasonic EZA series of chip RC electronic networks. These components are engineered for automotive, industrial, and consumer markets. The series offers various configurations to meet diverse filtering needs while maintaining a small form factor suitable for modern electronics manufacturing.

Replacement Considerations

Check Panasonic datasheets for alternative EZA series parts with matching 47Ω resistance and compatible capacitance values. Verify that any substitute maintains the same 0805 package dimensions and electrical ratings to ensure mechanical and functional compatibility.
