108-683JS

Overview

The Delevan 108-683JS is a surface-mount fixed inductor with a nominal inductance of 68 µH and a tolerance of ±5%. It features an unshielded construction utilizing a ferrite core. The component supports a maximum DC current of 32 mA and exhibits a maximum DC resistance of 23 Ohms. Designed for PCB mounting, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded SMD design for minimal magnetic interference
• Ferrite core construction for stable inductance
• Standard two-lead surface mount termination

Applications

• RF signal processing circuits
• General power filtering applications
• Telecommunications equipment

Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and generic Delevan. Confirm RoHS compliance status directly with the supplier, as documentation varies between lead-free and standard specifications. Ensure the unshielded topology aligns with your layout requirements to prevent coupling issues.

Selection Notes

Select this component when a compact, unshielded inductor is required for low-current RF or power paths. The high DC resistance limits suitability for high-power applications. Verify that the 32 mA current rating meets the circuit's operational demands without saturation.

Part Context

This part belongs to the Delevan fixed inductor portfolio, characterized by small form factors suitable for dense PCB layouts. The 108 series typically denotes specific dimensional constraints common in legacy or specialized RF modules.

Replacement Considerations

SRR0745A-680M (Bourns Inc.) is listed as a substitute option in distributor databases, though electrical parameters differ significantly.
