Procurement Notes

Verify RoHS compliance status as markings indicate 'R' prefix for compliant units. Confirm axial lead dimensions and molded package compatibility with assembly equipment. Check manufacturer datasheets for specific Q-factor and self-resonant frequency limits at operating frequencies.

Selection Notes

Select this component for low-inductance RF applications requiring unshielded performance. Ensure the 435 mA current rating meets circuit requirements. Consider the 10% tolerance for precision tuning needs. Verify thermal stability within the specified -55°C to +105°C range for the intended environment.

Part Context

Part of the Delevan 0819 series of fixed inductors. This series offers various inductance values in a standardized molded axial package. The 0819-24K specifically targets the 1 µH segment with high current capability relative to its size.

Replacement Considerations

Cross-reference with other 1 µH axial RF inductors from manufacturers like API Delevan or Coilcraft. Verify matching electrical parameters including DCR, current rating, and physical footprint before substitution.
