ELK-EV431FF

Overview

The Panasonic ELK-EV431FF is a surface-mount digital noise filter designed for EMI and RFI suppression. It integrates a coil-type ferrite bead with a varistor in a single package to provide combined filtering and electrostatic discharge (ESD) protection. The component features a capacitance of 430 pF and supports a maximum DC current of 2 A. It operates within a temperature range of -20°C to +85°C. The physical dimensions are 3.2 mm in length, 1.8 mm in width, and 2.2 mm in height, housed in a 1207 (3218 metric) SMD/SMT package.

Feature Summary

Integrates coil-type ferrite bead and varistor for combined EMI/RFI filtering and ESD protection
Designed specifically for suppressing digital noise in data lines
Surface-mount construction suitable for automated assembly processes

Applications

Data lines for mobile devices
LC and RC line protection circuits
General EMI/RFI suppression in electronic equipment

Procurement Notes

Verify the specific suffix and revision level against official Panasonic documentation to ensure compatibility with design requirements. Confirm that the 1207 package dimensions align with PCB footprint constraints. Check for any discontinued status or lifecycle notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when simultaneous EMI filtering and ESD protection are required in space-constrained applications. The integrated varistor offers enhanced transient voltage suppression compared to standard ferrite beads alone. Ensure the 2 A current rating meets the operational load of the target circuit without saturation.

Part Context

This part belongs to the Panasonic ELK-EV series of digital noise filters. The series focuses on providing compact solutions for high-speed signal integrity issues. These components are engineered to address electromagnetic interference in modern portable electronics where board real estate is limited.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult official Panasonic cross-reference guides or distributor databases for verified alternatives if this specific model is unavailable.
