103R-180K

Overview

The Delevan 103R-180K is a surface-mount RF inductor from the Micro i Chip series. It features an inductance of 18 nH with a tolerance of ±10%. The component has a maximum DC resistance of 93 mΩ and supports a maximum DC current of 1.03 A. It utilizes an unshielded design with phenolic core material, suitable for general-purpose RF applications.

Feature Summary

• Unshielded construction for minimal magnetic interference
• Phenolic core material for stable performance
• Surface-mount package for automated PCB assembly

Applications

• RF circuit filtering
• Impedance matching networks
• General-purpose RF signal processing

Procurement Notes

Verify the specific manufacturer source, as API Delevan assets are often managed by other entities. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the ordering suffix matches the required packaging format for production integration.

Selection Notes

Select this part for low-inductance RF applications requiring high current handling relative to its size. Compare the 93 mΩ DCR against circuit loss requirements. Consider the unshielded nature when placing components near sensitive analog traces to prevent coupling issues.

Part Context

This component belongs to the 103R series of Micro i Chip inductors. These parts are designed for compact RF designs where space is limited. The series offers various inductance values while maintaining consistent physical dimensions for board layout flexibility.

Replacement Considerations

Check for direct substitutes within the same 103R family or cross-reference with other manufacturers offering 18 nH SMD inductors with similar current ratings and DCR specifications.
