2773044446

Overview

Fair-Rite 2773044446 is a surface-mount ferrite bead designed for EMI suppression in high-frequency circuits. It features a compact 2-SMD J-lead package with dimensions of 1.6 mm length, 0.8 mm width, and 1.0 mm height. The component exhibits a DC resistance of 1.1 mΩ and an impedance of 40 Ω at 100 MHz. It operates reliably within a temperature range of -55°C to +125°C and complies with RoHS standards.

Feature Summary

• Compact surface-mount design suitable for automated assembly
• Low DC resistance minimizes signal loss in power lines
• High impedance characteristic effective for high-frequency noise attenuation

Applications

• Common mode noise reduction in data lines
• EMI filtering in portable electronic devices
• Signal integrity enhancement in high-speed digital circuits

Procurement Notes

Verify the specific impedance tolerance and material composition directly with Fair-Rite or authorized distributors before procurement. Confirm that the 2-SMD J-lead package variant matches your PCB footprint requirements. Ensure compliance with current RoHS directives and check for any recent lifecycle status updates from the manufacturer to avoid obsolescence risks during production planning.

Selection Notes

Select this component when space constraints require a small form factor SMD ferrite bead. The low 1.1 mΩ DC resistance makes it suitable for power supply lines where voltage drop must be minimized. The 40 Ω impedance at 100 MHz provides adequate attenuation for common EMI frequencies without significantly affecting lower frequency signals or DC performance.

Part Context

This part belongs to Fair-Rite's series of surface-mount ferrite beads, specifically engineered for integrated circuit decoupling and signal line protection. The 2773044446 model utilizes advanced ferrite materials to provide stable impedance characteristics across a wide temperature range, ensuring consistent performance in demanding electronic environments.

Replacement Considerations

Cross-reference with other 2-SMD J-lead ferrite beads offering similar 40 Ω @ 100 MHz impedance and comparable physical dimensions. Verify that alternative components maintain equivalent DC resistance and thermal stability ratings to ensure seamless integration without redesigning the PCB layout.
