0819-66K

Overview

The Delevan 0819-66K is a fixed axial leaded RF inductor with molded unshielded construction. It provides an inductance of 56 µH with a tolerance of 10% and a maximum DC resistance of 10 Ohms. The component supports a maximum DC current of 69 mA and achieves a minimum Q factor of 45. Its self-resonant frequency is 11.5 MHz, with physical dimensions of 5.08 mm length and 1.98 mm diameter.

Feature Summary

• Molded unshielded coil design for RF applications
• Axial lead termination for PCB mounting
• High Q factor performance at resonant frequencies

Applications

• RF circuit filtering
• Impedance matching networks
• Tuned oscillator circuits

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead availability and specific manufacturing lot details directly with the supplier or manufacturer API Delevan prior to ordering. Ensure the procurement channel provides valid traceability for this legacy component series.

Selection Notes

Select this component when a 56 µH value with 10% tolerance is required for RF environments. Consider the 69 mA current limit and 10 Ohm DC resistance against circuit requirements. Verify that the unshielded nature does not cause interference in dense layouts compared to shielded alternatives.

Part Context

Part of the Delevan 0819 series, which offers various inductance values in a standardized cylindrical molded package. This series is designed for general-purpose RF applications requiring axial leads. The 0819-66K specifically targets mid-range inductance needs within this family.

Replacement Considerations

Cross-reference with other 56 µH axial RF inductors from manufacturers like Coilcraft or Bourns if supply is limited. Ensure replacement parts match the 1.98 mm diameter and 5.08 mm length for board compatibility.
