108R-683FS

Overview

The Delevan 108R-683FS is a fixed surface-mount inductor designed for radio frequency applications. It features an unshielded construction with a nominal inductance of 68 µH and a tight tolerance of ±1%. The component supports a maximum DC current of 32 mA and exhibits a maximum DC resistance of 25 Ohms. It utilizes a nonstandard package configuration with two leads, suitable for PCB mounting in compact RF circuit designs.

Feature Summary

• Unshielded design minimizes magnetic interference coupling
• High precision tolerance ensures stable RF performance
• Surface-mount form factor enables automated assembly

Applications

• RF signal filtering circuits
• Impedance matching networks
• Radio frequency tuning stages

Procurement Notes

Verify the specific lead configuration against schematic requirements due to the nonstandard package designation. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the 32 mA current rating during operation.

Selection Notes

Select this component when high inductance values are required in a small footprint without shielding constraints. Compare against shielded alternatives if electromagnetic interference sensitivity exists. Validate that the 25 Ohm resistance meets voltage drop specifications within the target circuit topology.

Part Context

This part belongs to the Delevan fixed inductor family, specifically tailored for SMT RF applications. It complements other series like the 3094R and 1008R by offering distinct inductance and package options for diverse RF layout needs.
