Procurement Notes
Verify the manufacturer part number 0819-94J against official Delevan documentation to confirm specifications. Ensure compatibility with RoHS regulations as this component may contain lead. Confirm that the axial package and physical dimensions fit the target PCB layout. Validate electrical parameters such as inductance and current ratings against the system requirements before procurement.
Selection Notes
Select this component when a high-value 820 µH inductance is required in an unshielded axial form factor. Consider the low maximum DC current rating of 25.5 mA and high DC resistance of 72 Ohms during circuit design. Compare against other 0819 series variants if different inductance or tolerance values are needed. Ensure the self-resonant frequency aligns with the operating range.
Part Context
This component belongs to the Delevan 0819 series of RF inductors. These parts are characterized by their molded unshielded construction and axial leads. The series offers various inductance values tailored for radio frequency applications. The 0819-94J specifically provides a high inductance option within this lineup.
Replacement Considerations
The 0819R-94J is a documented substitute part number offering identical electrical characteristics including 820 µH inductance and 25.5 mA current rating.
