0819-66G

Overview

The Delevan 0819-66G is an unshielded molded axial RF inductor with a nominal inductance of 56 µH and a tolerance of ±2%. It features a maximum DC resistance of 10 Ω and a rated current of 69 mA. The component has a minimum Q factor of 40 at its self-resonant frequency of 7 MHz. It utilizes standard axial terminals for PCB mounting, with physical dimensions of 5.08 mm length and 1.98 mm diameter.

Feature Summary

• Unshielded molded construction for general RF applications
• Axial leaded termination style for through-hole PCB mounting
• Standard terminal configuration compatible with automated insertion

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify the specific ordering suffix to confirm tolerance and packaging details, as variations exist within the 0819 series. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as historical data indicates non-compliance for some variants in this family. Ensure the required inductance value and current rating align with the design specifications before procurement.

Selection Notes

Select this component when an unshielded axial inductor is required for RF frequencies around 7 MHz. Consider the 69 mA current limit and 10 Ω DC resistance for power budget calculations. The molded package offers mechanical stability but lacks magnetic shielding, making it suitable for applications where cross-talk is not a primary concern.

Part Context

The 0819-66G belongs to the Delevan 0819 series of fixed RF inductors. This series provides various inductance values ranging from low microhenries to high hundreds of microhenries, all sharing a consistent axial molded form factor. The part is designed for reliable performance in radio frequency environments.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Cross-reference other Delevan 0819 series parts with similar electrical parameters if available. Verify pin compatibility and thermal characteristics when considering alternative manufacturers.
