EZA-DT52AAAJ

Overview

The EZA-DT52AAAJ is a surface-mount RC (Pi) EMI filter circuit manufactured by Panasonic Industry. It features four channels with integrated resistors of 470 Ohms and capacitors of 47 pF per channel. The component operates within a voltage rating of 25 V and functions across a temperature range of -25°C to +85°C. Physically, it utilizes a 1206 (3216 metric) package with dimensions of 3.2 mm in length, 1.6 mm in width, and 0.65 mm in height. The device employs SMD/SMT termination types and is supplied in cut tape or reel packaging.

Feature Summary

• Integrates four independent low-pass filter channels within a single compact surface-mount package
• Utilizes RC (Pi) topology for effective electromagnetic interference suppression
• Designed specifically for signal line protection in mobile devices

Applications

• Mobile device data lines
• Wireless networking equipment
• Consumer electronics signal interfaces

Procurement Notes

Verify current availability status as the component is listed as End-of-Life (EOL). Confirm RoHS compliance details, as some sources indicate non-compliance. Check specific datasheet revisions for any changes in pinout or electrical characteristics before finalizing design integration. Ensure supply chain partners can provide valid traceability documentation given the discontinued status.

Selection Notes

Select this component when designing circuits requiring multi-channel EMI filtering for high-speed data lines in space-constrained applications. The 1206 footprint offers a balance between performance and board area efficiency. Consider the 470 Ohm resistance value for impedance matching requirements in USB or similar interfaces. Evaluate thermal management needs against the specified operating temperature range.

Part Context

This part belongs to the Panasonic EZA series of RC filter networks, designed for noise suppression in digital communication lines. The DT suffix typically denotes the specific package style and internal configuration within the broader EZAST family. These components are engineered to meet stringent EMC standards for portable electronic devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Due to the End-of-Life status, alternative components from other manufacturers must be evaluated based on identical electrical parameters (470 Ohm/47 pF, 4-channel) and mechanical footprint compatibility.
