ELK-EA100FA

Overview

The ELK-EA100FA is a surface-mount EMI filter manufactured by Panasonic Electronic Components. It utilizes LC (T-Type) technology to provide low-pass filtering capabilities for electronic circuits. The component features a rated voltage of 50V and a capacitance value of 10pF, with a cutoff frequency specification of 500MHz. It is housed in a 1207 (3218 Metric) package, measuring 3.2mm in length, 1.8mm in width, and 2.2mm in height. The device operates within a temperature range of -20°C to +85°C.

Feature Summary

• Provides effective attenuation of electromagnetic interference through LC T-type filter topology
• Designed for high-frequency noise suppression in sensitive digital signal lines
• Compact surface-mount construction facilitates automated assembly processes

Applications

• Data line protection for mobile devices
• High-speed interface circuit noise filtering
• Portable electronics signal integrity enhancement

Procurement Notes

Verify current availability status as the component may be subject to discontinuation or limited supply constraints. Confirm RoHS compliance documentation matches specific regional regulatory requirements. Ensure ordering suffixes align with exact packaging preferences such as cut tape or reel quantities. Validate that the 1207 package dimensions fit the designated PCB footprint without clearance issues.

Selection Notes

Select this component when a 10pF capacitance value and 500MHz cutoff frequency are required for low-pass filtering applications. The 50V rating suits standard low-voltage digital systems. Consider the 1207 package size for space-constrained designs requiring surface-mount integration. Evaluate thermal performance within the specified -20°C to +85°C operating range for environmental suitability.

Part Context

This part belongs to the ELK-EA series of EMI filters from Panasonic. The series offers various capacitance values and cutoff frequencies tailored for different noise suppression needs. The ELK-EA100FA specifically targets applications requiring precise low-pass characteristics with minimal signal distortion in high-speed data paths.

Replacement Considerations

Consult official Panasonic documentation for direct cross-references. Verify electrical equivalence regarding capacitance, cutoff frequency, and voltage ratings before substitution. Ensure physical package compatibility and thermal characteristics match the original design specifications.
