2743004111

Overview

Fair-Rite part number 2743004111 is an axial ferrite bead designed for electromagnetic interference suppression. It features a single-turn configuration with an impedance of 126 ohms at 100 MHz. The component utilizes Fair-Rite Material 43, optimized for high-frequency noise attenuation. Physical dimensions are 3.50 mm in diameter and 7.60 mm in length. It supports through-hole mounting for circuit board integration.

Feature Summary

• Provides effective common-mode noise suppression for signal and power lines
• Utilizes Material 43 composition for superior performance in the VHF/UHF range
• Axial leaded construction facilitates easy installation on printed circuit boards

Applications

• Suppression of radio frequency interference in data communication cables
• Noise filtering on high-speed digital signal lines
• EMI mitigation in consumer electronic device power inputs

Procurement Notes

Verify the specific impedance value and material grade against the manufacturer's current datasheet before finalizing procurement. Ensure the axial package dimensions match the target PCB footprint requirements. Confirm that the component meets all relevant environmental compliance standards required for the intended market.

Selection Notes

Select this component when axial mounting is preferred over surface mount alternatives. Material 43 is suitable for applications requiring significant attenuation above 30 MHz. Evaluate the DC resistance and saturation current to ensure compatibility with the operating current levels of the target circuit without causing signal degradation or thermal issues.

Part Context

This part belongs to the Ferrite Beads and Chips category within Fair-Rite's product portfolio. It serves as a passive component specifically engineered for EMI control. The axial form factor distinguishes it from chip-style beads, offering mechanical robustness for through-hole assembly processes commonly used in industrial and legacy equipment designs.

Replacement Considerations

Direct substitutes must match the 126-ohm impedance at 100 MHz and utilize Material 43. Verify physical lead spacing and overall length to ensure fitment. Alternative parts from other manufacturers should be evaluated for identical frequency response characteristics and current handling capabilities.
