Fixed Inductors Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm exact electrical tolerances and RoHS compliance status prior to ordering. Ensure that the axial lead configuration matches the target printed circuit board layout requirements. Confirm availability and lead times directly with authorized distributors as stock levels fluctuate.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 27 nH is required for high-frequency operation up to 875 MHz. The unshielded nature necessitates careful placement to minimize electromagnetic interference with adjacent components. Verify that the 2.2 A current rating meets the peak load requirements of the application circuit.

Fixed Inductors Part Context

This part belongs to the Delevan 1026 series of fixed inductors, which are characterized by their molded construction and axial leads. This series is engineered for demanding RF environments where consistent performance and mechanical robustness are critical. The 1026 series complements other Delevan offerings like the 1025 series, focusing on specific inductance ranges and current handling capabilities.

Fixed Inductors Replacement Considerations

Cross-reference with other 27 nH axial inductors from manufacturers such as Coilcraft or Bourns if supply constraints exist. Ensure substitute parts match the 875 MHz self-resonant frequency and 30 mOhm DCR specifications to maintain circuit performance.
