Feature Summary

• Unshielded construction for minimal magnetic interference
• High-frequency operation capability up to 2.6 GHz
• Surface-mount design for automated PCB assembly

Applications

• RF circuit filtering
• Impedance matching networks
• High-frequency signal processing

Procurement Notes

Verify the manufacturer designation as API Delevan or Delevan during sourcing. Confirm the specific tolerance suffix (JS) matches the required 5% specification. Ensure the package type corresponds to the standard 2-SMD no-lead configuration. Cross-reference datasheets for thermal performance limits.

Selection Notes

Select this component for applications requiring low inductance values in the nanohenry range. The high self-resonant frequency makes it suitable for UHF and microwave bands. Evaluate the 1.03 A current rating against peak load requirements. Consider the unshielded nature when layout spacing is critical.

Part Context

This part belongs to the 103 series of fixed RF inductors from API Delevan. These components are designed for general-purpose RF applications where small form factors are necessary.
