108-683H

Overview

The Delevan 108-683H is a surface-mount RF inductor designed for high-frequency applications. It features a fixed inductance of 68 uH with a tight tolerance of +/- 3%. The component exhibits a maximum DC resistance of 23 Ohms and a rated current capacity of 32 mA. Constructed with a ferrite core, it operates reliably within a temperature range of -55 C to +125 C. This unshielded SMD device is suitable for integration into compact electronic circuits requiring precise RF filtering or impedance matching characteristics.

Feature Summary

• Surface mount construction for automated PCB assembly
• Ferrite core design optimized for RF signal integrity
• Wide operational temperature range for environmental stability

Applications

• RF circuit filtering
• Impedance matching networks
• High-frequency signal processing

Procurement Notes

Verify the specific manufacturer source, as API Delevan assets have transitioned. Confirm RoHS compliance status directly with the supplier, as historical records may vary. Ensure the component meets current regulatory requirements for your target market before finalizing procurement decisions.

Selection Notes

Select this component when a 68 uH inductance with high precision (3%) is required for RF stages. Consider the low current rating (32 mA) and higher DC resistance (23 Ohms) relative to power inductors. Verify that the unshielded nature does not cause interference in dense layouts.

Part Context

This part belongs to the Delevan family of fixed surface-mount inductors. It utilizes standard SMD termination styles compatible with typical pick-and-place equipment. The ferrite core material distinguishes it from air-core alternatives, offering higher inductance density in a small footprint.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching inductance, tolerance, current rating, and physical dimensions.
