• Phenolic core material providing stable inductance characteristics

Fixed Inductors Applications

• RF circuit filtering
• Impedance matching networks
• General purpose inductive components in electronic assemblies

Fixed Inductors Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance for this specific part number. Confirm lead-free availability if required by project standards. Ensure the supplier provides official API Delevan datasheets to validate the 60 mOhm DCR and 1.5 A current ratings against counterfeit or obsolete stock.

Fixed Inductors Selection Notes

Select this component for low-inductance RF applications requiring axial leads. The 68 nH value and 850 MHz self-resonant frequency suit high-frequency circuits. Consider the unshielded nature when layout proximity to sensitive traces is a concern. Verify that the 1.5 A current rating meets the circuit's operational requirements without saturation.

Fixed Inductors Part Context

This part belongs to the Delevan 1026 series of fixed inductors. It utilizes a standard tubular molded construction common in legacy RF designs. The axial form factor distinguishes it from surface-mount alternatives like the SMD series, offering different mechanical integration options for older or specialized PCB layouts.

Fixed Inductors Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Similar axial inductors from other manufacturers may require verification of the 68 nH value, 60 mOhm DCR, and 1.5 A current rating to ensure functional equivalence.
