Fixed Inductors Procurement Notes

Verify the specific suffix 'F' indicates the required 1% tolerance variant, as other suffixes may denote different tolerances or specifications. Confirm RoHS3 compliance status for the specific batch. Ensure the axial lead form matches the target PCB layout requirements before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a precise 3.3 µH inductance with tight 1% tolerance is required for RF circuits. Consider the 285 mA current rating to ensure operation within safe thermal limits. The unshielded nature requires adequate spacing from sensitive components to prevent magnetic interference.

Fixed Inductors Part Context

This part belongs to the Delevan 1025R series of molded unshielded RF coils. The series offers various inductance values and tolerance options identified by alphanumeric suffixes. These components are standardized for high-frequency applications requiring stable inductive characteristics.

Fixed Inductors Replacement Considerations

Cross-reference with other 1025R series variants such as 1025R-32J (5% tolerance) if looser tolerance is acceptable. Verify that substitute parts match the 6.35 mm x 2.41 mm axial package dimensions and similar electrical parameters.
