EZA-DT23AAAJ

Overview

The Panasonic EZA-DT23AAAJ is a surface-mount RC pi-network filter designed for EMI suppression in data lines. It integrates two 47-ohm resistors with ±5% tolerance and one 100-pF capacitor with -20/+30% tolerance. The component operates within a rated voltage of 12V DC and an ambient temperature range of -25°C to +85°C. Housed in a compact 1608 (0603) package, it measures 1.6 x 0.8 x 0.6mm, facilitating high-density PCB layouts for mobile device applications.

Feature Summary

• Integrates dual resistors and a single capacitor into a unified pi-filter topology for effective common-mode noise attenuation.
• Optimized for signal integrity preservation on high-speed digital interfaces while suppressing electromagnetic interference.
• Utilizes a low-profile surface-mount design suitable for space-constrained portable electronics.

Applications

• Data line protection in mobile devices
• EMI filtering for USB interfaces
• Signal conditioning for MIPI connections

Procurement Notes

Verify the specific suffix 'DT' confirms the 47 ohm/100 pF configuration, as Panasonic EZA series variants differ by resistance and capacitance values. Ensure the ordering code matches the required tolerance specifications and package dimensions for your PCB footprint. Confirm the manufacturer source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a pi-network topology is required for EMI suppression on 12V-rated digital lines. The 47 ohm resistance value balances insertion loss with signal attenuation needs. Consider the -25°C to +85°C operating range against your environmental requirements. Verify that the 1608 package size fits your assembly constraints compared to larger alternatives like the ST or DT series variants.

Part Context

This part belongs to the Panasonic EZA-DT series of RC filters. It is distinct from the EZAST22AAAJ, which features different electrical parameters including 47pF capacitance and 47 ohm resistance but in a larger 1608 package with different physical dimensions. The DT series specifically targets compact mobile applications requiring integrated filtering solutions.

Replacement Considerations

Direct substitutes include other Panasonic EZA-DT series parts with identical 47 ohm/100 pF configurations. Cross-referencing with similar pi-network filters from other manufacturers requires verifying matching resistance, capacitance, and package dimensions to ensure functional compatibility.
