• Axial leaded termination for standard PCB mounting
• Fixed inductance design optimized for RF applications

Applications

• RF circuit filtering
• Impedance matching networks
• General radio frequency signal processing

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status, as documentation indicates non-compliance for some variants in this series. Confirm package availability details, such as reel quantities, directly with the manufacturer or authorized distributors prior to ordering. Ensure the axial lead form factor matches the target PCB layout requirements.

Selection Notes

Select this component when a fixed 6.8 µH inductance is required for RF circuits with moderate current handling needs up to 122 mA. The unshielded design necessitates careful placement to avoid magnetic coupling with adjacent components. Verify that the 27 MHz self-resonant frequency aligns with the operational bandwidth of the application.

Part Context

This part belongs to the Delevan 0819 series of leaded RF inductors. These components are characterized by their molded epoxy coating and axial leads, offering a robust solution for through-hole assembly. The series covers a range of inductance values tailored for various radio frequency applications.

Replacement Considerations

Cross-reference with other 6.8 µH axial RF inductors if sourcing constraints exist. Ensure replacement parts match the 122 mA current rating and 3.2 Ohm DCR limits. Verify physical dimensions (5.08 x 1.98 mm) fit the existing footprint.
