103R-332GS

Overview

The Delevan 103R-332GS is an unshielded surface-mount RF inductor with a nominal inductance of 3.3 µH and a tolerance of 1%. It features a maximum DC resistance of 1.4 Ohms and supports a maximum DC current of 260 mA. The component has a minimum Q factor of 24 at its self-resonant frequency of 70 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded wirewound construction for RF applications
• Surface-mount design with standard terminations
• High self-resonant frequency capability

Applications

• RF circuit filtering
• Impedance matching networks
• General-purpose electronic circuits requiring fixed inductance

Procurement Notes

Verify the specific suffix (e.g., GS) against official manufacturer documentation to confirm terminal type and packaging configuration. Ensure compatibility with PCB footprint dimensions of 2.54 mm by 2.54 mm. Confirm RoHS status and lead-free compliance requirements prior to integration into final assemblies.

Selection Notes

Select this component when a 3.3 µH inductance value is required with tight 1% tolerance. Consider the 260 mA current rating and 1.4 Ohm DC resistance for power handling limits. The unshielded nature requires layout consideration to minimize electromagnetic interference coupling with adjacent components.

Part Context

This part belongs to the Delevan 103/R series of RF inductors. These components are designed for surface-mount technology (SMT) applications. The series offers various inductance values within a standardized small outline package format suitable for high-density board layouts.

Replacement Considerations

Cross-reference with other Delevan 103 series variants such as 103-332KS or 103-332F if different tolerances or packaging options are needed. Verify that substitute parts maintain identical electrical parameters and physical footprint constraints.
