103R-392GS

Overview

The Delevan 103R-392GS is an unshielded surface-mount RF inductor with a nominal inductance of 3.9 µH and a tolerance of ±2%. It features a maximum DC resistance of 1.55 Ohms and a rated current of 250 mA. The component utilizes a nonstandard two-lead package configuration for PCB mounting.

Feature Summary

Unshielded wirewound construction designed for radio frequency applications
Nonstandard two-lead termination format for specific board layouts
Surface-mount technology compatible installation

Applications

RF circuit filtering
Impedance matching networks
General purpose RF signal processing

Procurement Notes

Verify the physical package dimensions against standard footprint libraries, as this part uses a nonstandard two-lead configuration rather than typical SMD pads. Confirm that the 250 mA current rating meets the design requirements to prevent saturation or thermal issues during operation.

Selection Notes

Select this component when a 3.9 µH unshielded inductor is required in a specialized two-lead form factor. Consider the 1.55 Ohm DC resistance impact on circuit efficiency. Ensure the nonstandard package geometry aligns with available PCB real estate and assembly capabilities.

Part Context

This part belongs to the 103R series of RF inductors manufactured by Delevan. It is distinct from shielded variants like the S1812R series and differs from standard SMD packages by utilizing a unique lead structure suitable for specific high-frequency mounting needs.
