Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the axial lead configuration and physical dimensions align with your PCB footprint requirements. Ensure the 39 mA current rating meets your circuit's operational demands to prevent saturation or overheating during operation.

Selection Notes

Select this component when a high-inductance value is required within a compact axial form factor for RF applications. Consider the 6.6 MHz self-resonant frequency limit to ensure suitability for your target operating range. Evaluate the 30.5 Ohm DC resistance impact on circuit efficiency and verify that the 39 mA current handling capacity exceeds your peak load requirements.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values in a consistent molded axial package. These components are engineered for reliability in radio frequency environments, providing stable performance across standard operating conditions while maintaining a small physical profile for dense circuit board layouts.

Replacement Considerations

Cross-reference with other Delevan 0819 series variants for different inductance values. Verify equivalent specifications from other manufacturers offering axial RF inductors with similar 270 µH ratings, ensuring compatibility with the 5.08 mm x 1.98 mm package dimensions and 30.5 Ohm resistance limits.
