High precision inductance with ±1% tolerance for critical circuit tuning
Robust thermal stability across extended industrial temperature ranges

Applications

RF signal processing circuits
Impedance matching networks
Filter design in communication systems

Procurement Notes

Verify the manufacturer part number against official API Delevan documentation to ensure authenticity. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration. Check RoHS compliance status as indicated in the latest datasheet. Ensure the supplier provides traceability documentation consistent with original manufacturing standards.

Selection Notes

Select this component when high precision and low DC resistance are required for unshielded RF applications. The 330 nH value and 620 mA rating suit moderate current RF paths. Consider the non-standard lead form factor during PCB layout planning. Compare self-resonant frequency limits against operating bandwidth requirements to avoid parasitic resonance issues.

Part Context

This component belongs to the Delevan family of fixed RF inductors. It is specifically engineered for surface-mount technology integration. The product line emphasizes reliability in radio frequency environments. It serves as a passive filtering element within electronic assemblies requiring precise inductive values.
