2773021446

Overview

The Fair-Rite 2773021446 is a surface-mount ferrite bead designed for high-frequency noise suppression. It utilizes Fair-Rite Material 73, which provides effective damping characteristics in the VHF and UHF spectrum. The component features an impedance of 78 Ohms measured at a test frequency of 25 MHz. It supports a maximum current rating of 5 Amperes with a low DC resistance of 0.0012 Ohms. The physical dimensions are 9.6 mm in length, 8.0 mm in width, and 6.0 mm in height. This axial-lead equivalent SMD package allows for direct board mounting.

Feature Summary

• Utilizes Fair-Rite Material 73 for superior high-frequency attenuation performance
• Supports high-current applications up to 5 Amperes with minimal resistive loss
• Provides compact surface-mount footprint for automated assembly integration

Applications

• High-speed digital signal line filtering
• Power supply output noise suppression
• RF interference mitigation in communication equipment

Procurement Notes

Verify manufacturing status as this part number may be subject to discontinuation or limited availability. Confirm exact material composition and impedance tolerance against current datasheet revisions before finalizing design specifications. Ensure supplier documentation matches the specific Fair-Rite product code to avoid substitution errors with similar series components.

Selection Notes

Select this component when high current handling capability is required alongside significant impedance at 25 MHz. Material 73 is optimal for frequencies above 100 MHz where other materials may exhibit lower loss. Compare thermal dissipation requirements against the 5A rating and ensure PCB copper area supports adequate heat spreading for continuous operation.

Part Context

This component belongs to the Fair-Rite 27730 series of surface-mount ferrite beads. It serves as a solid-state alternative to traditional axial-lead ferrite beads, offering improved mechanical stability for modern PCB layouts. The series is engineered for consistent magnetic properties across varying temperature ranges.
