EZA-NT55AAAJ

Overview

The EZA-NT55AAAJ is a surface-mount RC (Pi) EMI filter manufactured by Panasonic Industry. It features a fourth-order low-pass configuration with four channels, each containing a 470 Ohm resistor and a 470 pF capacitor. The component operates within a rated voltage of 50V and functions reliably across a temperature range of -25°C to 85°C. Housed in a 2512 (6432 Metric) concave package measuring 6.40mm x 3.20mm x 1.00mm, it is designed for data line protection in mobile devices.

Feature Summary

• Provides effective electromagnetic interference suppression through a fourth-order RC Pi network topology.
• Integrates four independent signal channels for multi-line data protection.
• Utilizes a compact surface-mount form factor suitable for space-constrained mobile device designs.

Applications

• Data lines for mobile devices
• Portable electronic equipment signal integrity protection
• Consumer electronics interface filtering

Procurement Notes

Verify the specific suffix AA against official Panasonic documentation to confirm exact capacitance and resistance tolerances. Confirm current availability status as components may be subject to discontinuation or lifecycle changes. Ensure the selected package variant matches the required PCB footprint dimensions and mounting specifications for the target application design.

Selection Notes

Select this component when designing circuits requiring robust EMI filtering for high-speed data interfaces in portable electronics. The 50V rating and 470 Ohm impedance are critical parameters for maintaining signal integrity while attenuating noise. Verify that the 2512 package size aligns with the board layout constraints and thermal management requirements of the final assembly process.
