ELK-EA220FA

Overview

The ELK-EA220FA is a third-order low-pass LC (T-Type) EMI digital noise filter manufactured by Panasonic. It features a capacitance value of 22 pF and a cutoff frequency of 300 MHz. The component supports a maximum DC current of 6 A and operates within a temperature range of -20°C to +85°C. Rated at 50V, it utilizes SMD/SMT termination in a 1207 package.

Feature Summary

• Third-order low-pass filtering technology for effective noise suppression
• High current handling capability suitable for power-sensitive lines
• Compact surface-mount design for space-constrained layouts

Applications

• Data lines for mobile devices

Procurement Notes

Verify the obsolete part status before procurement planning. Confirm availability through authorized distributors as supply may be limited. Ensure the 1207 package dimensions match the target PCB footprint. Validate that the 6 A current rating meets the specific circuit requirements. Check for RoHS compliance documentation if required by regional regulations.

Selection Notes

Select this component when third-order attenuation is necessary for high-frequency noise reduction. The 300 MHz cutoff frequency suits applications requiring sharp signal integrity preservation above this threshold. Ensure the 22 pF capacitance does not interfere with signal timing or impedance matching in the specific data line application.

Part Context

This component belongs to the ELK-EA series of ferrite beads and EMI filters from Panasonic Industry. The series includes various models with different capacitance and current ratings. The ELK-EA220FA specifically addresses high-current data line protection needs using an LC topology rather than simple resistive ferrite beads.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements should be verified against electrical specifications including cutoff frequency, capacitance, and current rating.
