0819-28F

Overview

The Delevan 0819-28F is a leaded RF inductor featuring an axial termination style and unshielded molded construction. It provides an inductance of 1.5 uH with a tight tolerance of 1%. The component supports a maximum DC current of 310 mA and exhibits a maximum DC resistance of 490 mohms. Designed for PCB mount applications, it operates within the radio frequency spectrum.

Feature Summary

• Axial leaded configuration for through-hole mounting
• Unshielded molded coil design
• High precision 1% inductance tolerance

Applications

• RF circuit filtering
• Impedance matching networks
• Radio frequency signal processing

Procurement Notes

Verify the specific manufacturer datasheet to confirm RoHS compliance status and environmental certifications prior to integration. Ensure that the axial lead dimensions align with the target printed circuit board layout constraints. Confirm that the 310 mA current rating meets the operational requirements of the intended RF application without saturation.

Selection Notes

Select this component when high precision is required for RF circuits due to its 1% tolerance. The unshielded design necessitates careful placement to avoid magnetic interference with nearby components. Consider the axial form factor for manual or wave soldering processes where surface mount alternatives are unsuitable.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values with different tolerance grades, indicated by suffix letters. The 0819-28F specifically denotes the 1.5 uH value with 1% tolerance, distinguishing it from other variants in the family such as those with 2% or 3% tolerances.

Replacement Considerations

The 0819R-28F serves as a potential substitute within the same product line, offering identical electrical characteristics but potentially differing in packaging or specific manufacturing revisions. Verify mechanical footprint compatibility before substitution.
