Fixed Inductors Procurement Notes

Verify component authenticity against official API Delevan documentation. Confirm RoHS compliance status and specific manufacturing lot details prior to integration. Ensure storage conditions align with manufacturer guidelines to maintain electrical performance and physical integrity throughout the supply chain process.

Fixed Inductors Selection Notes

Select this component for applications requiring stable 33 µH inductance in unshielded configurations. Consider the 130 mA current rating and 24 MHz self-resonant frequency limits. Verify thermal requirements against the -55°C to +125°C operating range. Axial leads facilitate standard PCB mounting techniques.

Fixed Inductors Part Context

Part of the 1025R series, designed for reliable RF performance. Manufactured by API Delevan, known for established reliability standards. The molded variant offers durability compared to standard wirewound types. Suitable for high-frequency circuits where shielding is not required.

Fixed Inductors Replacement Considerations

Cross-reference with other 33 µH axial RF inductors if availability is constrained. Verify that substitute parts match the 3.4 Ohm DCR and 130 mA current limits. Ensure physical dimensions and lead spacing are compatible with existing footprints.
