• Utilizes Material 73 composition for effective noise attenuation across the 25-300 MHz frequency spectrum
• Provides high impedance characteristics specifically optimized for common mode noise reduction applications
• Features axial lead construction suitable for through-hole mounting on printed circuit boards

Applications

• Electromagnetic interference filtering in electronic circuits
• Noise suppression on signal and power lines
• Common mode choke applications in communication equipment

Procurement Notes

Verify that the specific order matches the manufacturer part number 2773009112 to ensure receipt of the correct Material 73 axial ferrite bead. Confirm that the application environment remains within the specified operating temperature limits of -55°C to +125°C. Ensure that the circuit design accounts for the component's physical dimensions and axial lead spacing requirements during assembly.

Selection Notes

Select this component when high impedance attenuation is required in the VHF band, specifically around 25 MHz. Material 73 is appropriate for applications involving digital signals or switching power supplies generating noise in the 25-300 MHz range. Choose the axial form factor if through-hole mounting is mandated by the board layout constraints or mechanical stability requirements.

Part Context

This component belongs to Fair-Rite's line of passive ferrite beads, which are essential for EMI mitigation. The product series utilizes specific magnetic materials tailored for distinct frequency bands. Material 73 is engineered to provide high permeability and loss characteristics in the VHF region, distinguishing it from materials optimized for lower or higher frequencies.

Replacement Considerations

Substitute only with components explicitly documented as electrically equivalent in terms of impedance profile and material composition. Verify that any alternative part maintains the same axial package dimensions and lead configuration to ensure mechanical compatibility.
