Procurement Notes

Verify the specific manufacturer part number 2518061018Y0 against official Fair-Rite documentation to confirm exact electrical characteristics and physical dimensions. Ensure compatibility with standard SMT reflow processes and check for RoHS compliance status through authorized distributors or direct manufacturer channels before finalizing procurement specifications.

Selection Notes

Select this component when a 1806 footprint is required for space-constrained designs needing 100 ohm impedance at 100 MHz. Confirm that the 400 mA current rating meets the operational requirements of the target circuit. Evaluate thermal management needs given the 125°C maximum operating temperature limit and ensure the PCB layout accommodates the specified 4.5 x 1.6 mm outline.

Part Context

This component is part of Fair-Rite's Series 25 ferrite chip beads, which are engineered for surface mount integration. These beads utilize multi-layer ceramic technology to provide significant impedance in small packages, addressing EMI challenges in modern electronics where board real estate is limited and high-frequency noise control is critical.

Replacement Considerations

Cross-reference with other Series 25 parts like 2518061017Y0 for similar impedance profiles. Verify pinout compatibility and dimensional tolerances before substituting any alternative components from different manufacturers.
