2504021026Y0

Overview

Fair-Rite Products Corp. part number 2504021026Y0 is a multi-layer chip ferrite bead designed for surface-mount applications. It belongs to the 25 series and utilizes SMD/SMT termination types within an 0402 (1005 metric) package. The component provides an impedance of 100 ohms at 100 MHz with a maximum DC current rating of 50 mA. Electrical characteristics include a tolerance of 25 percent and a maximum DC resistance of 1 ohm. The device operates reliably within a temperature range from -55 degrees Celsius to +125 degrees Celsius, ensuring stability in demanding electronic environments.

Feature Summary

• Multi-layer construction enables compact footprint integration for high-density circuit boards
• Surface-mount design facilitates automated assembly processes
• Solid-state filtering eliminates mechanical wear associated with snap-on cores

Applications

• High-frequency noise suppression on data lines
• Power supply decoupling in portable electronics
• EMI mitigation in mobile communication devices

Procurement Notes

Verify the specific suffix Y0 against official Fair-Rite documentation to confirm material composition and impedance tolerances. Ensure the selected variant matches the required 0402 package dimensions and thermal ratings for your specific PCB layout constraints before finalizing orders.

Selection Notes

Select this component when board space is limited and through-hole mounting is not feasible. Compare the 50 mA current limit against peak load requirements to prevent saturation. Evaluate the 100 ohm impedance profile against target noise frequencies to ensure effective attenuation without signal degradation.

Part Context

This component is part of Fair-Rite's extensive portfolio of passive filtering solutions. It complements larger cable ferrites by providing discrete filtering capabilities directly on the substrate. The product line supports various industrial and commercial standards, including RoHS compliance for global market deployment.

Replacement Considerations

Cross-reference equivalent 0402 ferrite beads from other manufacturers based on identical impedance curves and current ratings. Verify that substitute parts maintain compatible termination metallurgy and thermal expansion coefficients to ensure reliable solder joint integrity during reflow processes.
