Fixed Inductors Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm RoHS compliance status as documentation may indicate non-compliance. Ensure the axial package dimensions match the target PCB footprint requirements. Validate that the 230 mA current rating meets the operational demands of the intended circuit design.

Fixed Inductors Selection Notes

Select this component when an unshielded axial inductor with 20 µH inductance is required for RF environments. The 5% tolerance provides precise control over circuit characteristics. Consider the physical size constraints given the 11.1 mm length and 4.75 mm diameter. Ensure the application does not require shielding to prevent interference with adjacent components.

Fixed Inductors Part Context

This part belongs to the Delevan ER1840 series, which consists of established reliability RF inductors. These components are characterized by their unshielded design and axial leads, making them suitable for general-purpose RF applications where compactness and standard mounting are prioritized over magnetic shielding.

Fixed Inductors Replacement Considerations

Cross-reference with other Delevan ER1840 variants such as ER1840-136JP if a 5% tolerance is acceptable. Verify compatibility with alternative manufacturers offering similar 20 µH axial RF inductors, ensuring matching DC resistance and current ratings.
