0819-10K

Overview

The Delevan 0819-10K is a leaded RF inductor from the 0819 series, featuring a molded unshielded coil design. It offers an inductance of 270 nH with a 10% tolerance and a maximum DC current rating of 525 mA. The component exhibits a maximum DC resistance of 0.38 Ohms, a minimum Q factor of 30, and a self-resonant frequency of 440 MHz. Physically, it measures 5.08 mm in length and 1.98 mm in diameter, utilizing axial termination for PCB mounting.

Feature Summary

• Molded unshielded construction for consistent RF performance
• Axial leaded termination for standard PCB integration
• High self-resonant frequency capability

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm axial lead dimensions and molding material specifications against target assembly requirements. Ensure supplier provides valid manufacturer traceability for quality assurance protocols.

Selection Notes

Select this model for applications requiring 270 nH inductance with moderate current handling up to 525 mA. Consider the unshielded design for thermal management or when magnetic interference is not critical. Compare Q factor and SRF against operating frequency needs.

Part Context

Part of the Delevan 0819 series of leaded RF inductors. Variants include different tolerances such as 0819-10F (1%) and 0819-10J (5%), sharing identical electrical parameters except for tolerance specifications. The series utilizes iron core materials for general-purpose RF applications.

Replacement Considerations

Direct substitutes within the same series include 0819-10F and 0819-10J, which share identical inductance, current, and resistance values but differ in tolerance precision.
