2773007112

Overview

The Fair-Rite 2773007112 is an axial leaded ferrite bead constructed with 73 material composition. It provides a nominal impedance of 115 Ohms at a test frequency of 25 MHz. The component operates within a temperature range of -55°C to +125°C. Physical dimensions include a length of 8.9 mm and a diameter of 3.5 mm, with a unit weight of approximately 600 mg. It is available in cut tape or reel packaging formats.

Feature Summary

• Utilizes 73 material composition for specific high-frequency noise suppression characteristics
• Features axial leads designed for through-hole mounting applications
• Provides defined impedance performance at standard test frequencies

Applications

• Electromagnetic interference (EMI) filtering in electronic circuits
• Noise suppression on signal and power lines
• Common mode choke applications requiring axial termination

Procurement Notes

Verify the exact impedance value and material grade against the manufacturer's current datasheet, as distributor listings may contain conflicting specifications such as 132 Ohms. Confirm the required packaging format, whether cut tape or reel, matches your assembly equipment capabilities. Ensure the axial lead style is compatible with your printed circuit board layout and drilling specifications before finalizing the order.

Selection Notes

Select this component when axial termination is required for ferrite bead integration into a design. The 73 material selection indicates suitability for specific frequency ranges where this composition offers optimal loss characteristics. Consider the physical size constraints of the 8.9 mm length and 3.5 mm diameter during the mechanical design phase to ensure adequate clearance on the PCB.

Part Context

This part belongs to the Fair-Rite 27 series of ferrite beads. The series designation typically correlates with the specific magnetic material formulation used, which dictates the impedance profile across different frequencies. Axial leaded variants are distinct from surface mount chips, offering easier manual prototyping and robust mechanical attachment for certain industrial environments.

Replacement Considerations

Direct substitutes must match the 73 material composition and axial form factor. Verify that any alternative part maintains the same impedance curve at 25 MHz and fits within the 8.9 mm x 3.5 mm dimensional envelope. Cross-referencing with other Fair-Rite axial beads in the 27 series may provide options if availability is constrained.
