Overview
The Fair-Rite Products Corp. model 2761019447 is a surface-mount ferrite bead designed for differential-mode noise suppression. It utilizes Fair-Rite material 61 and features a 2-SMD J-lead package with an 1812 [4532 Metric] footprint. The component exhibits an impedance of 36 ohms at 100 MHz and 50 ohms at 250 MHz, with a maximum DC resistance of 0.8 milliohms. Operating temperatures range from -55°C to +125°C.
Feature Summary
- Surface-mount construction with J-leads for automated assembly
- Material 61 composition optimized for high-frequency differential-mode attenuation
- Low DC resistance to minimize signal loss in power or data lines
Applications
- Differential-mode EMI suppression in high-speed digital circuits
- Noise filtering on USB, HDMI, and other high-speed interface traces
- Power line filtering in compact electronic assemblies
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official Fair-Rite datasheet prior to integration. Confirm that the 1812 package dimensions align with your PCB land pattern requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer part number to avoid confusion with similar surface-mount ferrite components.
Selection Notes
Select this component when differential-mode noise reduction is required rather than common-mode suppression. Material 61 provides effective attenuation in the VHF/UHF spectrum. The low DC resistance makes it suitable for applications where minimal voltage drop is critical. Verify that the surface-mount form factor fits within the available board space constraints.
Part Context
This component belongs to Fair-Rite's surface-mount ferrite bead series, distinct from their through-hole cable cores. It is engineered specifically for printed circuit board integration, offering a compact solution for high-frequency interference management in dense electronic designs.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternative surface-mount ferrites with matching 1812 footprints and comparable Material 61 characteristics if sourcing issues arise.
