Overview
The Fair-Rite 2643004801 is a solid free-hanging ferrite core bead utilizing 43-grade material. It features a cylindrical shape with an inner diameter of 0.86 mm (0.034 inches) and an outer diameter of 2.03 mm (0.080 inches). The component has a length of 2.67 mm (0.105 inches). It provides a minimum impedance of 31 ohms at 100 MHz, designed for EMI suppression in high-frequency common-mode choke applications.
Feature Summary
- Utilizes 43-grade ferrite material for effective high-frequency noise attenuation
- Solid free-hanging design suitable for direct cable attachment
- Guaranteed minimum impedance specification for controlled EMI suppression performance
Applications
- High frequency common-mode chokes
- EMI suppression on cables
- Inductive noise filtering applications
Procurement Notes
Verify the specific suffix '01' indicates a non-burnished finish as per Fair-Rite part number conventions. Confirm that the 31-ohm impedance value meets the minimum requirements for your target frequency range. Ensure the 0.86 mm inner diameter accommodates the conductor size without mechanical stress. Cross-reference the datasheet to confirm the material grade matches the intended electromagnetic interference profile.
Selection Notes
Select this component when a compact, solid ferrite bead is required for high-frequency noise reduction. The 43 material grade is optimal for frequencies above 10 MHz. Consider the physical dimensions to ensure fit within the assembly constraints. Verify that the impedance characteristics align with the specific noise spectrum being suppressed in the circuit design.
Part Context
This part belongs to the Fair-Rite Shield Bead series, which offers guaranteed impedance specifications. These components are distinct from standard ferrite cores by providing verified performance data for EMI suppression. The 43 material is widely used for its balanced permeability and resistivity properties in broadband noise control scenarios.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult Fair-Rite technical support for equivalent materials or dimensional alternatives if exact replacement is required.
