Procurement Notes

Verify the specific suffix designation when ordering, as variations such as LF indicate RoHS compliance status which may differ from the base part number. Confirm that the required operating temperature range aligns with the specified -55 °C to +105 °C limits. Ensure the axial lead dimensions match the target PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a compact, unshielded inductor with precise low-nanohenry values. The axial form factor facilitates easy manual or automated placement on printed circuit boards. Consider the 1.025 A current rating and 140 mΩ DC resistance when designing power stages to ensure thermal stability under load conditions.

Part Context

This component belongs to the Gowanda 10M series of standard RF inductors. The series offers various inductance values ranging from 0.1 µH to higher capacities, all sharing similar physical dimensions and mounting characteristics. The 10M220J specifically targets the lower end of the inductance spectrum for high-frequency signal processing tasks.

Replacement Considerations

Cross-reference with other Gowanda 10M series parts for different inductance values. Verify compatibility with alternative manufacturers offering similar axial wirewound inductors, ensuring matching electrical parameters and physical footprint dimensions are maintained.
