Overview
The Fair-Rite 2518127008Y3 is a multilayer ferrite chip bead designed for surface-mount applications. It belongs to the Series 25 product line and utilizes an 1812 (4532 metric) package with SMD/SMT termination style. The component provides an impedance of 80 ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 3 A and features a maximum DC resistance of 40 mohms. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Multilayer construction for compact surface-mount integration
- High current handling capability suitable for power lines
- Solid core design for consistent electromagnetic interference suppression
Applications
- Power supply filtering
- Battery charger circuits
- Portable electronic devices
- Energy-efficient system protection
Procurement Notes
Verify the specific impedance value and tolerance against the manufacturer's official datasheet, as distributor listings may vary in accuracy. Confirm that the 1812 package dimensions align with your PCB footprint requirements. Ensure the selected component meets RoHS3 compliance standards if required by your manufacturing specifications. Cross-reference the part number with the original Fair-Rite documentation to confirm availability and technical validity before finalizing procurement decisions.
Selection Notes
Select this component when space constraints require an 1812 surface-mount form factor. The 3 A current rating makes it appropriate for power delivery paths where significant DC bias is present. Verify that the 80 ohm impedance at 100 MHz matches the target noise frequency spectrum. Ensure the operating temperature range covers the environmental conditions of the final assembly.
Part Context
This component is part of Fair-Rite's Series 25 ferrite chip beads, which are engineered for high-performance electromagnetic interference suppression in dense circuit boards. The multilayer technology allows for higher capacitance and inductance values in small packages compared to traditional single-layer beads.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Fair-Rite technical support or authorized distributors for verified equivalents.
