105-332G

Overview

The Delevan 105-332G is a fixed RF inductor designed for surface-mount technology applications. It features an unshielded wirewound construction with a ferrite core, housed in a nonstandard two-lead package measuring approximately 2.54 mm by 2.54 mm with a height of 1.91 mm. The component provides an inductance of 3.3 µH with a tolerance of ±2%. It supports a maximum DC current of 210 mA and exhibits a maximum DC resistance of 2.2 Ohms. Key electrical characteristics include a minimum Q factor of 25 and a self-resonant frequency of 62 MHz, making it suitable for high-frequency circuit integration.

Feature Summary

• Unshielded wirewound design utilizing ferrite core material for stable RF performance
• Surface-mount termination style optimized for PCB mounting efficiency
• High self-resonant frequency capability ensuring effective operation in RF signal paths

Applications

• RF signal processing circuits
• Impedance matching networks
• Filtering components in radio frequency systems

Procurement Notes

Verify RoHS compliance status carefully as records indicate variations between lead-free and lead-containing versions. Confirm the specific manufacturing batch details to ensure alignment with project environmental requirements. Cross-reference the datasheet version to validate the exact tolerance and current ratings prior to final procurement decisions.

Selection Notes

Select this component when an unshielded SMD inductor with precise 3.3 µH value is required for RF applications. Ensure the PCB layout accommodates the specific nonstandard footprint dimensions. Verify that the 210 mA current rating meets the operational demands of the target circuit without causing saturation or excessive thermal generation.

Part Context

This part belongs to the broader category of fixed RF inductors manufactured by API Delevan. It shares functional similarities with other models in the 105 series, such as the 105-332HS, though packaging and tolerance specifications may differ. The product line focuses on providing reliable passive components for specialized electronic filtering and tuning needs.

Replacement Considerations

The 105-332HS is a documented variant within the same family, offering similar electrical parameters but potentially different tolerance or packaging constraints. Verify mechanical fit and electrical equivalence before substitution.
