• High precision 1% inductance tolerance
• Surface-mount design for automated PCB assembly

Fixed Inductors Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF applications

Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets are often managed by other entities. Confirm RoHS compliance status directly with the supplier, as historical data indicates potential variations. Ensure the ordering suffix matches the required packaging format. Cross-reference the part number against current distributor catalogs to confirm active lifecycle status before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when precise inductance values are critical for RF signal integrity. The unshielded design requires careful layout consideration to prevent coupling with nearby traces. Evaluate the 245 mA current limit against peak operational loads. Compare thermal performance at the specified 1.25 Ohm resistance against alternative shielded options if electromagnetic compatibility is a primary constraint.

Fixed Inductors Part Context

This part belongs to the 3090R series of fixed RF inductors manufactured by Delevan. The series typically offers various inductance values in standard SMD footprints. These components are designed for high-frequency applications requiring stable electrical characteristics over a wide temperature range.

Fixed Inductors Replacement Considerations

Direct substitutes include the 3090R-182G (±2% tolerance) or 3090R-182J (±5% tolerance). Alternative manufacturers may offer equivalent 1.8 µH unshielded SMD inductors, but verify pinout compatibility and Q-factor specifications.
