Fixed Inductors Procurement Notes

Verify the specific ordering suffix against official Viking Tech documentation to ensure correct packaging and terminal configuration. Confirm that the requested quantity aligns with standard tape and reel requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 18 nH is required for high-speed signal paths. Consider the 700 mA current rating and 170 mΩ DCR for power handling needs. Ensure the 0603 package dimensions fit the PCB layout constraints. Evaluate the 3.1 GHz self-resonant frequency to confirm suitability for the target operating bandwidth without parasitic resonance issues.

Fixed Inductors Part Context

This component belongs to the Viking Tech WL series of fixed inductors. The series offers various inductance values and current ratings within standardized surface-mount packages. The WL03GT18N specifically addresses the need for small-form-factor inductors with precise tolerances and high self-resonant frequencies for modern high-density electronics.

Fixed Inductors Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that alternative components match the 18 nH inductance, 0603 package size, and similar current ratings. Ensure replacement parts maintain comparable self-resonant frequency characteristics to preserve circuit performance.
