Overview
Fair-Rite 2743021447 is a surface-mount ferrite chip bead designed for electromagnetic interference suppression. It features a single-line configuration with J-leads in a 2-SMD package. The component utilizes Material 43, providing an impedance of 105 Ohms at 100 MHz and a maximum DC resistance of 1.2 milliohms. Physical dimensions are 9.60 mm in length by 3.05 mm in width, with a maximum height of 3.05 mm. It operates within a temperature range of -55°C to 125°C.
Feature Summary
- Surface-mount construction with J-lead termination for reliable PCB attachment
- Material 43 composition optimized for high-frequency noise attenuation
- Low DC resistance design minimizes signal loss in power lines
Applications
- High-speed data line filtering
- Power supply output decoupling
- General EMI suppression in compact electronics
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact impedance tolerance and packaging type. Ensure the selected variant matches the required RoHS compliance status and moisture sensitivity level for your assembly process. Cross-reference the part number with official Fair-Rite documentation to avoid substitution errors.
Selection Notes
Select this component when space constraints require a surface-mount solution for single-line noise reduction. The Material 43 formulation is suitable for frequencies around 100 MHz. Evaluate the 1.2 milliohm DC resistance to ensure it meets the voltage drop requirements of the target circuit without affecting performance.
Part Context
This part belongs to the Fair-Rite ferrite chip bead family, which provides passive filtering solutions for modern electronic assemblies. These components are engineered to suppress common-mode and differential-mode noise in compact form factors, supporting the miniaturization trends in consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative suppliers by matching impedance values, physical footprint, and material characteristics before implementation.
