0819-04F

Overview

The Delevan 0819-04F is a leaded RF inductor from the 0819 series, featuring an axial termination style and unshielded molded construction. It offers an inductance of 0.15 uH with a tight 1% tolerance. The component supports a maximum DC current of 760 mA and has a maximum DC resistance of 0.18 ohms. Designed for PCB mounting, it operates within a standard temperature range and utilizes a reel packaging format for automated assembly processes.

Feature Summary

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

Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing components

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations may exist between bulk and reel formats. Confirm RoHS compliance status prior to integration, as historical data indicates potential non-compliance for certain variants within this manufacturer's portfolio. Cross-reference the manufacturer part number with distributor catalogs to validate current production status and availability constraints.

Selection Notes

Select this component when precise low-inductance values are required for high-frequency signal paths. The 1% tolerance ensures consistent performance in sensitive RF designs. Consider the axial form factor for manual or wave soldering workflows where surface mount alternatives are unsuitable. Evaluate the 760 mA current rating against peak load requirements to prevent saturation.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. Similar models include the 0819-10F and 0819-48F, which share the same physical dimensions and mounting style but differ significantly in inductance and current ratings. The series is characterized by its molded unshielded construction and axial leads, catering to specialized radio frequency engineering needs.

Replacement Considerations

Direct substitutes within the same series include the 0819R-04F, which shares identical electrical specifications but may differ in manufacturing revisions or packaging details. Verify that any alternative component matches the 0.15 uH inductance, 1% tolerance, and 0.18 ohm DCR to maintain circuit integrity.
