2508051217Z3

Overview

The Fair-Rite 2508051217Z3 is a multilayer ferrite chip bead designed for surface mount applications. It operates in the 0805 (2012 metric) package size with dimensions of 2 mm length, 1.25 mm width, and 0.9 mm height. The component provides an impedance of 120 Ohms at 100 MHz and supports a maximum DC current of 3A. It features a low maximum DC resistance of 50 mOhms and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer construction for high-frequency signal suppression
• Surface mount design compatible with standard SMT processes
• Capable of handling high DC currents up to 3A

Applications

• High-speed data line filtering
• Power supply noise suppression
• Signal integrity enhancement in compact electronics

Procurement Notes

Verify the specific suffix 'Z3' against official Fair-Rite documentation to confirm exact impedance tolerance and packaging specifications. Ensure compatibility with RoHS3 standards and check for any specific handling requirements related to the multilayer ceramic structure during assembly.

Selection Notes

Select this component when space constraints require an 0805 footprint but higher current capacity than standard beads offers. The 120 Ohm impedance at 100 MHz suits broadband noise attenuation. Confirm that the 3A current rating aligns with the circuit's operational load to prevent saturation or excessive heating.

Part Context

This part belongs to Fair-Rite's 25 series of multilayer ferrite chip beads. These components are engineered for board-level EMI suppression, offering a compact alternative to through-hole solutions while maintaining effective noise reduction characteristics in dense PCB layouts.

Replacement Considerations

Direct substitutes include other 0805 multilayer ferrite beads with similar 120 Ohm @ 100MHz impedance and 3A current ratings from Fair-Rite or other manufacturers, provided pinout and thermal characteristics match.
