108R-683G

Overview

The Delevan 108R-683G is a surface-mount RF inductor with an inductance of 68 µH and a tolerance of ±2%. It features a maximum DC resistance of 25 Ohms and a rated current of 32 mA. The component utilizes an unshielded design within a nonstandard SMD package measuring approximately 2.5 x 2.5 mm.

Feature Summary

• Unshielded wirewound construction for specific RF applications
• High precision ±2% inductance tolerance
• Surface-mount termination style

Applications

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

Procurement Notes

Verify the exact physical dimensions and lead configuration against the official datasheet, as sources describe the package as nonstandard or 2.5x2.5mm. Confirm availability status directly with the manufacturer or authorized distributors, as inventory levels vary significantly across suppliers.

Selection Notes

Select this component when high precision is required for RF circuits due to its tight ±2% tolerance. Ensure the PCB layout accommodates its specific nonstandard footprint and verify that the 32 mA current rating meets the application's operational requirements without saturation.

Part Context

This part belongs to the Delevan fixed inductor portfolio, designed for surface-mount technology. It serves as a specialized passive component for radio frequency environments where standard shielding is not mandated, distinguishing it from shielded power inductor variants in the same series.

Replacement Considerations

Cross-reference with other Delevan 108R series parts for similar electrical characteristics. Verify mechanical compatibility before substituting with generic equivalents, as the nonstandard package dimensions may limit direct pin-to-pin replacements.
