Overview
The Fair-Rite 2952778301 is an eight-lead through-hole ferrite bead designed for EMI and RFI noise suppression in multi-line circuits. It features a radial termination style and operates within a temperature range of -55°C to +125°C. The component provides an impedance of 338 Ohms at the specified test frequency, effectively attenuating high-frequency interference across multiple signal paths simultaneously.
Feature Summary
- Eight-lead configuration for simultaneous multi-line noise suppression
- Radial through-hole termination for standard PCB mounting
- High impedance performance for effective EMI/RFI attenuation
Applications
- Multi-conductor cable noise filtering
- Data bus line protection
- Power supply input filtering
Procurement Notes
Verify the specific impedance value and lead configuration against the official datasheet before integration. Confirm that the radial through-hole package aligns with the target PCB footprint design. Ensure the operating temperature range meets the environmental requirements of the final assembly application.
Selection Notes
Select this component when simultaneous suppression across multiple parallel lines is required. The eight-lead design simplifies routing compared to discrete single-lead beads. Verify that the physical size accommodates the available board space and that the through-hole mounting method is compatible with the manufacturing process.
Part Context
This part belongs to the Fair-Rite PC Bead series, which utilizes specific ferrite materials optimized for broadband noise absorption. These components are engineered for robust performance in demanding electronic environments, providing reliable signal integrity maintenance in complex circuit designs requiring multi-channel filtering.
Replacement Considerations
Check for equivalent eight-lead ferrite beads from other manufacturers. Ensure substitute parts match the radial lead spacing and overall dimensions. Verify that alternative components offer comparable impedance characteristics at the target frequency.
