- Axial leaded termination for through-hole PCB mounting
- High precision 1% inductance tolerance
Applications
- RF circuit filtering
- Impedance matching networks
- General radio frequency signal processing
Procurement Notes
Verify the specific suffix designation during procurement to ensure compliance with required tolerance levels and packaging configurations. Confirm RoHS status as documentation indicates non-compliance for this variant. Validate that the axial lead form factor aligns with the target printed circuit board layout requirements before finalizing orders.
Selection Notes
Select this component when precise 2.2 uH inductance is required in high-frequency environments. The low DC resistance minimizes power loss, while the unshielded design necessitates careful placement to avoid magnetic coupling with adjacent components. Ensure the operating current remains below the 257 mA limit to maintain stability.
Part Context
This part belongs to the Delevan 0819 series of RF inductors. The series offers various inductance values with different tolerance codes, where the 'F' suffix typically denotes a 1% tolerance level. These components are engineered for stable performance in demanding radio frequency applications requiring reliable signal integrity.
Replacement Considerations
The 0819-32H serves as a direct substitute if a 3% tolerance is acceptable. Verify that the physical footprint and lead spacing remain compatible with existing PCB designs when considering alternative manufacturers or series.
