ELK-EA102FA

Overview

The Panasonic ELK-EA102FA is a surface-mount EMI filter belonging to the ELKEA series, designed for digital noise suppression. It utilizes an LC T-Type low-pass technology with a capacitance value of 1000pF and a cutoff frequency of 7MHz. The component operates within a temperature range of -20°C to +85°C and supports a maximum DC current of 5A. Rated at 50V, it features SMD/SMT termination in a 1207 (3218 metric) package measuring 3.2mm x 1.8mm x 2.2mm.

Feature Summary

• Integrates LC T-Type filtering architecture for effective electromagnetic interference suppression
• Engineered specifically for high-current data line applications up to 5A
• Compact surface-mount design suitable for space-constrained mobile device layouts

Applications

• Data lines for mobile devices
• Digital noise filtering in portable electronics
• EMI suppression in compact communication modules

Procurement Notes

Verify component authenticity through official Panasonic Industry channels or authorized distributors. Confirm RoHS compliance status and check for End-of-Life notices, as availability may be restricted. Ensure storage conditions maintain integrity prior to assembly. Validate package markings against datasheet specifications to prevent counterfeit substitution during procurement processes.

Selection Notes

Select this component when designing circuits requiring combined inductive and capacitive filtering for high-speed data lines. The 1000pF capacitance and 7MHz cutoff frequency make it suitable for specific bandwidth requirements. Consider the 5A current rating for power handling needs and ensure the 1207 footprint aligns with PCB layout constraints. Verify thermal performance within the specified operating temperature range.

Part Context

This ferrite bead belongs to the Panasonic ELKEA series, which focuses on coil-type EMI digital noise filters. The series provides solutions for suppressing electromagnetic interference in compact electronic systems. The ELK-EA102FA specifically addresses noise reduction in mobile device data lines using integrated LC topology rather than simple ferrite impedance.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Panasonic Industry technical support for direct replacements or cross-reference options compatible with the ELKEA series specifications.
