• Iron core material providing stable inductance characteristics
• Epoxy encapsulated design for environmental protection

Applications

• RF signal processing circuits
• General purpose inductive filtering
• High-frequency circuit tuning

Procurement Notes

Verify the specific ordering suffix 'G' against the manufacturer's official documentation to confirm lead-free status and RoHS compliance details. Ensure the package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 2.7 µH unshielded inductor is required for RF applications. Consider the 2 Ohm DCR limit and 220 mA current rating to ensure compatibility with the circuit's power and signal integrity requirements.

Part Context

This part belongs to the API Delevan 105 series of fixed inductors. It shares the same electrical specifications as the 105-272F but differs in the ordering suffix, which may indicate variations in packaging or specific manufacturing lot attributes.

Replacement Considerations

The 105-272F is a confirmed substitute with identical electrical parameters including 2.7 µH inductance and 2 Ohm DCR.
