EZA-DT31AAAJ

Overview

The EZA-DT31AAAJ is a surface-mount RC (Pi) EMI filter manufactured by Panasonic Electronic Components. It features four channels with a resistance of 100 Ohms and capacitance of 22 pF per channel. The component utilizes a 1206 package with long side terminals and operates at a voltage rating of 12 V. Designed as a first-order low-pass filter, it integrates resistor-capacitor networks for signal integrity.

Feature Summary

• Integrates RC Pi-filter topology for effective EMI suppression
• Provides four independent filtering channels in a compact form factor
• Features long side terminals to enhance solder joint reliability

Applications

• Data lines for mobile devices
• Wireless networking equipment
• Embedded systems requiring signal noise reduction

Procurement Notes

Verify the specific suffix and terminal configuration against the official datasheet to ensure compatibility with your PCB layout. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the 1206 footprint matches your design constraints before ordering.

Selection Notes

Select this component when designing circuits that require integrated low-pass filtering for high-speed data lines. The 100 Ohm resistance and 22 pF capacitance values are suitable for attenuating high-frequency noise while maintaining signal integrity. Consider the 12 V rating and SMD packaging for space-constrained applications.

Part Context

This part belongs to the Panasonic EZA series of passive components, specifically designed for EMI/RFI filtering applications. It represents a move towards miniaturized solutions that combine multiple discrete components into a single surface-mount device, simplifying assembly and improving performance consistency in consumer electronics.

Replacement Considerations

Cross-reference with similar 4-channel RC filters in the 1206 package from other manufacturers if supply is limited. Ensure equivalent electrical parameters, particularly the 100 Ohm resistance and 22 pF capacitance, are maintained to preserve circuit functionality.
