Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact tolerance and parameter specifications. Ensure that the selected variant matches the required electrical performance criteria for the target application. Cross-reference part numbers carefully to avoid confusion between similar series components with differing ratings.
Selection Notes
Select this component based on its 10 µH inductance value and 95 mA current handling capability. Consider the 47 MHz self-resonant frequency limit when designing high-frequency circuits. The axial package requires appropriate PCB layout considerations for spacing and mounting orientation compared to surface-mount alternatives.
Part Context
This component belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values with different tolerance options, utilizing a consistent molded axial form factor. This specific model represents a mid-range inductance option within the family, balancing size constraints with standard RF performance requirements.
Replacement Considerations
The 0819-48F is a verified substitute offering identical physical dimensions but with 1% tolerance instead of 5%. Verify compatibility regarding the tighter tolerance requirement before substitution.
