EZA-NT56AAAJ

Overview

The Panasonic EZA-NT56AAAJ is a surface-mount RC Pi low-pass filter designed for EMI/RFI suppression. It operates with a rated voltage of 50V and features a resistance value of 470 Ohms and a capacitance value of 1000pF. The component utilizes an RC (Pi) technology structure to attenuate high-frequency noise. Its physical dimensions are 0.252 inches in length by 0.122 inches in width, equivalent to 6.40mm x 3.10mm. This passive component belongs to the EZANT series and is intended for signal line protection applications.

Feature Summary

• Integrates resistive and capacitive elements within a single SMD package for compact circuit design
• Provides low-pass filtering characteristics to suppress electromagnetic interference on signal lines
• Utilizes RC Pi topology for effective high-frequency noise attenuation

Applications

• Signal line EMI suppression in electronic circuits
• RFI filtering for sensitive data interfaces
• Noise reduction in consumer electronics signal paths

Procurement Notes

Verify component authenticity through official Panasonic channels or authorized distributors. Confirm RoHS compliance status as documentation may indicate non-compliance depending on manufacturing date. Check lifecycle status as the part is listed as obsolete; ensure availability meets project requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 470 Ohm resistor and 1000pF capacitor combination is required in a Pi-filter configuration. Ensure the operating voltage does not exceed 50V. Consider the specific 6.40mm x 3.10mm footprint during PCB layout. Verify that the low-pass cutoff frequency aligns with the target signal bandwidth requirements.

Part Context

This component is part of the Panasonic EZA series of passive filters. It serves as a specialized solution for integrating filtering functions directly into signal traces without requiring discrete components. The EZANT series focuses on providing standardized filter values in compact surface-mount packages for modern electronics manufacturing.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is listed as obsolete, alternative solutions must be sourced from current Panasonic product lines or other manufacturers offering similar RC Pi filter specifications.
