2518068008Y3

Overview

The Fair-Rite 2518068008Y3 is a multi-layer ferrite chip bead designed for surface-mount applications. It operates within the 1806 (4516 metric) package, measuring 4.5 mm in length, 1.6 mm in width, and 1.6 mm in height. The component provides an impedance of 80 ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 3 A and maintains a maximum DC resistance of 40 mohms. The device functions reliably across a temperature range of -55°C to +125°C.

Feature Summary

• Multi-layer construction for effective conducted EMI signal suppression
• Surface-mount design compatible with automated placement processes
• High current handling capability suitable for dense circuit board packaging

Applications

• Electromagnetic interference suppression in cellular phones
• Noise filtering in computer systems
• Signal integrity management in laptops

Procurement Notes

Verify RoHS compliance status and lead times directly with Fair-Rite or authorized distributors before procurement. Confirm that the specific suffix Y3 matches project requirements for material composition and termination finish. Ensure storage conditions adhere to manufacturer guidelines to maintain component integrity prior to assembly.

Selection Notes

Select this component when high current capacity is required alongside moderate impedance values in compact layouts. The 1806 footprint offers a balance between thermal performance and space efficiency. Verify that the 3 A rating exceeds the peak operational currents of the target circuit lines to prevent saturation or excessive heating during normal operation.

Part Context

This part belongs to Fair-Rite's 25 series of multi-layer ferrite beads. These components are engineered to provide cost-effective noise suppression solutions. The series utilizes specialized ferrite materials optimized for high-frequency attenuation while maintaining low DC resistance to minimize power loss in power delivery networks.

Replacement Considerations

Check Fair-Rite datasheets for other parts in the 251806 series with identical 1806 dimensions and similar impedance characteristics. Ensure any substitute maintains the same 3 A current rating and operating temperature range to guarantee mechanical and electrical compatibility.
