2508052027Y1

Overview

The Fair-Rite 2508052027Y1 is a MultLyr chip ferrite bead designed for signal line EMI suppression. It features an 0805 (2012 metric) surface-mount package with dimensions of 2.00mm length, 1.25mm width, and 1.10mm maximum height. The component provides an impedance of 2 kOhms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current rating of 1A and has a maximum DC resistance of 0.3 ohms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer construction for compact signal line filtering
• High current handling capability up to 1A
• Low DC resistance for minimal signal loss
• RoHS compliant manufacturing

Applications

• Signal line EMI suppression in electronic circuits
• Noise filtering on high-speed data lines
• Power supply input/output decoupling

Procurement Notes

Verify the specific suffix 'Y1' against official Fair-Rite documentation to confirm the 1A current rating and 0.3-ohm DCR specifications. Ensure the ordering code matches the required packaging format, as suffixes may indicate reel or cut tape variations. Confirm RoHS compliance status directly from the manufacturer's datasheet before finalizing procurement.

Selection Notes

Select this component when a 0805 footprint is required for signal integrity protection. The 1A rating distinguishes it from lower-current variants like the 2508052027Z0. Consider the 2 kOhm impedance value for target noise frequencies around 100 MHz. Verify that the 0.3-ohm DCR meets the voltage drop requirements of the specific circuit application.

Part Context

This part belongs to the Fair-Rite 25 series of multilayer ferrite beads. These components are engineered for surface-mount technology applications requiring reliable EMI attenuation in space-constrained designs. The series offers various impedance and current ratings to suit different signal line requirements.

Replacement Considerations

The 2508052027Z0 is a related variant but differs significantly in current rating (200mA vs 1A) and DC resistance (400 mohms vs 300 mohms). Direct substitution requires verifying that the lower current capacity of the Z0 variant does not compromise circuit operation.
