Overview
Fair-Rite 2673000301 is a solid round cable ferrite core belonging to the 26 series, utilizing 73 material composition. Designed as an EMI suppression shield bead, it provides an impedance of 35 ohms at a test frequency of 25 MHz. The component features a 1.3 mm inner diameter and a 3.5 mm outer diameter, with an external length of 3.25 mm. It operates effectively within a frequency range up to 50 MHz and is supplied in bulk packaging.
Feature Summary
- Solid construction for secure mounting on cables
- 73 material composition optimized for high-frequency noise suppression
- Shield bead design for targeted EMI reduction
Applications
- Electromagnetic interference suppression on signal lines
- Noise filtering on small diameter cables
- Board component integration for EMI control
Procurement Notes
Verify the specific impedance value and physical dimensions against the official Fair-Rite datasheet before procurement. Confirm that the 73 material composition aligns with the target frequency requirements for the intended application. Ensure the solid core geometry fits the cable diameter constraints.
Selection Notes
Select this part when a compact, solid ferrite bead is required for high-frequency noise attenuation. The 73 material offers specific permeability characteristics suitable for the 25 MHz test frequency. Consider the 1.3 mm inner diameter limit when choosing between this model and larger bore alternatives.
Part Context
This component is part of the Fair-Rite 26 series of free-hanging ferrite cores. It serves as a passive suppression element distinct from openable snap-on cores or axial leaded beads. The 73 material designation indicates a manganese-zinc ferrite formulation tailored for broadband noise absorption.
Replacement Considerations
Direct substitutes include other Fair-Rite 26 series beads with identical 73 material properties and compatible physical dimensions. Verify that alternative models maintain the same 35 ohm impedance profile at 25 MHz to ensure equivalent circuit performance.
