2522181818Y5

Overview

The Fair-Rite 2522181818Y5 is a multilayer chip ferrite bead designed for conducted electromagnetic interference (EMI) suppression in single signal lines. It features a 2220 (5750 Metric) surface-mount package and utilizes Fair-Rite Series 25 materials. The component provides an impedance of 180 Ohms at 100 MHz, with a maximum DC current rating of 5 A and a maximum DC resistance of 42 mOhms.

Feature Summary

• Multilayer construction for compact EMI filtering
• High current handling capability suitable for power and signal lines
• Surface-mount design for automated assembly

Applications

• Conducted EMI suppression in single signal lines
• Portable electronic devices requiring compact filtering
• Automotive electronics systems

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Fair-Rite datasheet prior to procurement. Confirm that the 2220 package dimensions align with the target PCB footprint. Ensure the selected variant matches the required 5 A current rating for the intended circuit application to prevent performance degradation.

Selection Notes

Select this component when space constraints necessitate a 2220 package size while requiring significant current handling up to 5 A. The 180 Ohm impedance at 100 MHz targets common noise frequencies in digital circuits. Evaluate thermal management requirements, as high current flow through the low DC resistance generates heat within the multilayer structure during operation.

Part Context

This part belongs to the Fair-Rite Series 25 family of multilayer chip beads. These components are engineered to provide cost-effective EMI suppression solutions. The Series 25 line offers various impedance and current ratings to accommodate diverse signal integrity needs across consumer, industrial, and automotive sectors.

Replacement Considerations

Cross-reference with other Fair-Rite Series 25 parts offering similar 180 Ohm impedance and 5 A current ratings in the 2220 package. Verify equivalent DC resistance and physical dimensions before substituting to ensure mechanical fit and electrical performance parity.
