103R-122H

Overview

The Delevan 103R-122H is a fixed, unshielded surface-mount RF inductor with an inductance of 1.2 µH and a tolerance of ±3%. It features a maximum DC resistance of 740 mΩ and a rated current of 360 mA. The component utilizes a ferrite core and is housed in a non-standard package with two leads, suitable for PCB mounting.

Feature Summary

• Unshielded construction for general-purpose RF applications
• Ferrite core material for stable inductance
• Surface-mount design with standard terminations

Applications

• RF circuit filtering
• Impedance matching networks
• General-purpose signal processing

Procurement Notes

Verify the specific package dimensions against your PCB footprint, as this component uses a non-standard form factor distinct from common metric sizes. Confirm that the 360 mA current rating meets your circuit requirements to prevent saturation or overheating during operation.

Selection Notes

Select this part when an unshielded inductor is required to minimize cost or size constraints where magnetic shielding is not critical. Ensure the 1.2 µH value aligns with your target frequency response and that the 740 mΩ DC resistance does not introduce excessive loss in your power path.

Part Context

This component belongs to the Delevan 103 series of fixed inductors. It is designed for surface-mount technology (SMT) assembly, offering a compact solution for high-frequency applications where unshielded performance is acceptable.

Replacement Considerations

The 103-122H is a related variant within the same series, sharing similar electrical characteristics but potentially differing in physical package or lead configuration. Verify mechanical compatibility before substitution.
