0819-90F

Overview

The Delevan 0819-90F is a fixed axial leaded RF inductor with molded unshield construction. It provides an inductance of 560 µH with a tolerance of 1%. The component features a maximum DC resistance of 60 Ohms and supports a maximum DC current of 28 mA. Key electrical characteristics include a minimum Q factor of 45 and a self-resonant frequency of 3.3 MHz. Physical dimensions are 5.08 mm in length and 1.98 mm in diameter, with standard axial terminals for PCB mounting.

Feature Summary

• Molded unshielded coil design for RF applications
• Axial leaded termination style for through-hole PCB mounting
• High precision 1% inductance tolerance

Applications

• RF circuit filtering
• Signal processing networks
• Impedance matching circuits

Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance. Confirm package quantity requirements, typically supplied in reels of 1000 units. Ensure the specific ordering suffix matches the required tolerance and packaging configuration before finalizing procurement orders.

Selection Notes

Select this component for high-precision RF applications requiring strict 1% inductance tolerance. Evaluate the 28 mA current limit and 60 Ohm DC resistance against circuit load requirements. Consider the 3.3 MHz self-resonant frequency to ensure operation remains below the resonant point for intended signal frequencies.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values with axial leads and molded cases. The 0819-90F specifically targets applications needing higher inductance within the 560 µH range while maintaining tight manufacturing tolerances for consistent performance.

Replacement Considerations

Cross-reference other 0819 series variants for different inductance or tolerance needs. Verify that substitute components match the 5.08 mm length and 1.98 mm diameter physical constraints for PCB footprint compatibility.
