The component exhibits a maximum DC resistance of 0.85 ohms and supports a maximum DC current of 112 mA. Electrical performance includes a minimum Q factor of 45 and a self-resonant frequency of 100 MHz. Physical dimensions are 5.08 mm in length and 1.98 mm in diameter, designed for PCB mount applications.
Feature Summary
- Molded unshielded coil construction for RF applications
- Axial leaded termination style for standard PCB mounting
- High Q factor and defined self-resonant frequency characteristics
Applications
- RF circuit filtering
- Signal processing networks
- Impedance matching stages
Procurement Notes
Verify the specific electrical parameters against the official manufacturer datasheet prior to integration. Confirm that the axial leaded package and molded unshielded form factor align with the target PCB layout constraints. Ensure the maximum DC current rating of 112 mA meets the operational requirements of the intended circuit path without saturation risks.
Selection Notes
Select this component when a low-inductance value near 2.7 uH is required for high-frequency RF environments. The unshielded design necessitates careful placement to avoid magnetic coupling with adjacent components. Verify that the 0.85 ohm DC resistance does not introduce excessive voltage drop or power loss in the signal path during normal operation.
Part Context
This part belongs to the Delevan 0819 series of leaded RF inductors. The series offers various inductance values tailored for radio frequency applications. Components in this family share common physical dimensions and mounting styles, facilitating standardized design processes across different circuit configurations requiring specific RF impedance characteristics.
Replacement Considerations
Cross-reference with other 2.7 uH leaded RF inductors from manufacturers such as Coilcraft or Bourns. Ensure substitute parts match the 5.08 mm length and 1.98 mm diameter for mechanical compatibility. Verify equivalent Q factor and self-resonant frequency specifications to maintain circuit performance integrity.
