Overview
The Fair-Rite 2508051217Y3 is a multilayer chip ferrite bead designed for conducted EMI suppression in single signal lines. It utilizes an 0805 (2012 metric) surface-mount package with SMD/SMT termination. The component provides an impedance of 120 ohms at 100 MHz and supports a maximum DC current of 3 A. It features a maximum DC resistance of 50 milliohms and a tolerance of ±25%. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Multilayer construction for effective high-frequency noise attenuation
- Designed specifically for single signal line applications
- Surface-mount form factor suitable for automated assembly
Applications
- Conducted EMI suppression in electronic circuits
- Signal line filtering in compact devices
- Noise reduction in power and data transmission paths
Procurement Notes
Verify the specific suffix Y3 against official Fair-Rite documentation to confirm material composition and packaging details. Ensure compatibility with standard reflow soldering profiles for 0805 components. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and RoHS compliance before finalizing procurement plans.
Selection Notes
Select this component when space constraints require an 0805 footprint for EMI filtering. The 3 A current rating makes it suitable for moderate current signal lines. Verify that the 120 ohm impedance profile matches the target noise frequency spectrum. Consider the low DC resistance to minimize voltage drop across the filtered line during normal operation.
Part Context
This component belongs to the Fair-Rite Series 25, which offers a broad selection of cost-effective multilayer chip beads. These products are engineered to suppress conducted electromagnetic interference signals efficiently. The series provides various impedance values and current ratings to accommodate diverse circuit requirements while maintaining a small physical profile.
Replacement Considerations
Check Fair-Rite datasheets for other Series 25 parts with matching 0805 dimensions and similar impedance characteristics. Verify that alternative components support the required 3 A current handling and operate within the specified temperature range.
