0819-32K

Overview

The Delevan 0819-32K is a fixed axial leaded RF inductor with molded unshield construction. It features an iron core and offers a nominal inductance of 2.2 µH with a tight tolerance of ±2%. The component supports a maximum DC current of 257 mA and maintains a maximum DC resistance of 720 mOhms. Key electrical characteristics include a minimum Q factor of 45 and a self-resonant frequency of 130 MHz. Designed for PCB mounting, it measures 5.08 mm in length and 1.98 mm in diameter.

Feature Summary

• Molded unshielded design utilizing an iron core for stable RF performance
• Axial leaded termination style suitable for standard PCB mounting
• High Q factor and controlled self-resonant frequency for RF applications

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF inductors

Procurement Notes

Verify the specific ordering suffix to confirm tolerance and packaging details, as variations exist within the series. Confirm RoHS compliance status prior to integration, as some variants in this family are non-compliant. Ensure the required reel quantity aligns with distributor minimum order requirements. Cross-reference the datasheet for exact thermal ratings and soldering profiles to prevent component damage during assembly processes.

Selection Notes

Select this component when a 2.2 µH inductance value is required with a ±2% tolerance. The 257 mA current rating dictates suitability for low-to-moderate power RF stages. The unshielded nature requires careful layout consideration to minimize electromagnetic interference with adjacent components. Verify that the 130 MHz self-resonant frequency meets the operational bandwidth requirements of the target circuit design.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. These components are characterized by their cylindrical molded body and axial leads. The series provides various inductance values tailored for radio frequency applications, offering consistent performance across different manufacturing batches while maintaining standardized physical dimensions for board space efficiency.

Replacement Considerations

The 0819-32H is a documented alternative within the same series, sharing identical physical dimensions but featuring a ±3% tolerance instead of ±2%. Both parts share the same 2.2 µH inductance, 257 mA current rating, and 720 mOhm DC resistance specifications.
