Overview
The Fair-Rite 2743002111 is an axial ferrite bead on lead designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, providing a characteristic impedance of 158 ohms at 100 MHz. The component features a single-turn configuration with an overall length of 8.9 mm. It operates reliably within a temperature range of -55°C to +125°C and complies with RoHS standards.
Feature Summary
- Axial leaded construction for through-hole mounting
- Material 43 composition for high-frequency noise attenuation
- Integrated design combining magnetic core and leads
Applications
- Electromagnetic interference suppression in electronic circuits
- Common mode noise filtering on signal lines
- Power line noise reduction in low-voltage applications
Procurement Notes
Verify the specific material grade and impedance tolerance against the manufacturer's datasheet before integration. Confirm that the axial lead spacing and overall dimensions fit the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly.
Selection Notes
Select this component when a pre-assembled axial ferrite solution is preferred over separate snap beads or toroids. Material 43 is suitable for general-purpose EMI suppression in the VHF/UHF range. Verify that the current rating and saturation characteristics are sufficient for the application's signal or power levels.
Part Context
This part belongs to the Fair-Rite ferrite bead on lead series, offering a convenient alternative to discrete cores. It integrates the magnetic material directly onto the leads, simplifying assembly compared to split-core or snap-bead alternatives. The product line focuses on standardized sizes for common wire gauges.
Replacement Considerations
Direct substitutes include other axial ferrite beads from Fair-Rite with similar impedance profiles, such as those in the 27xx series. Cross-manufacturer replacements require matching the 158-ohm impedance at 100 MHz and ensuring compatible lead dimensions and thermal ratings.
