Overview
The Delevan 0819-24G is a fixed axial leaded RF inductor with a nominal inductance of 1 µH and a tolerance of ±2%. It features an iron core and tubular construction, providing a maximum DC resistance of 1.2 Ohms. The component supports a maximum DC current of 350 mA and achieves a minimum Q factor of 40 at its self-resonant frequency of 100 MHz. Designed for PCB mounting, it measures 5.08 mm in length and 1.98 mm in diameter.
Feature Summary
- Molded unshielded coil design for general-purpose RF applications
- Iron-core construction for stable inductance characteristics
- Axial lead termination style suitable for through-hole PCB mounting
Applications
- RF circuit filtering
- Impedance matching networks
- General-purpose signal processing
Procurement Notes
Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead-free availability if required by project specifications. Validate that the standard lead dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a 1 µH inductance with tight 2% tolerance is required for RF circuits. Ensure the operating current remains below the 350 mA limit to prevent saturation. Consider the unshielded nature of the design regarding potential magnetic interference with nearby sensitive components on the board layout.
Part Context
This part belongs to the Delevan 0819 series of molded unshielded RF inductors. The series offers various inductance values ranging from sub-microhenry to tens of microhenries, all sharing consistent physical dimensions and axial lead configurations for standardized integration into electronic assemblies.
Replacement Considerations
Cross-reference with other 1 µH axial RF inductors from manufacturers such as Coilcraft or Bourns. Verify that substitute parts meet the same 350 mA current rating and 100 MHz self-resonant frequency constraints to maintain circuit performance integrity.
