105R-681H

Overview

The Delevan 105R-681H is a surface-mount RF inductor with an inductance of 680 nH and a tolerance of 3%. It features an unshielded design housed in a non-standard, two-lead package. The component has a maximum DC resistance of 620 mOhms and a rated current of 395 mA. It operates within a temperature range of -55°C to +105°C.

Feature Summary

• Unshielded construction for minimal magnetic interference
• Surface-mount technology for automated PCB assembly
• Stable performance across wide industrial temperature ranges

Applications

• RF signal processing circuits
• Impedance matching networks
• Filtering applications in communication equipment

Procurement Notes

Verify the specific package dimensions against your PCB footprint, as this part uses a non-standard two-lead configuration rather than a standard SMD land pattern. Confirm RoHS compliance status with the manufacturer prior to ordering, as legacy components may have varying environmental certifications. Ensure the rated current meets your circuit's peak load requirements.

Selection Notes

Select this component when a compact, unshielded RF inductor is required for high-frequency applications. The 680 nH value suits specific impedance matching needs. Consider the non-standard package size during layout planning. Verify that the 395 mA current rating aligns with your system's operational limits to prevent saturation or overheating.

Part Context

This component belongs to Delevan’s fixed inductor series, designed for radio frequency applications. It serves as a passive energy storage element in electronic circuits, specifically tailored for RF filtering and tuning tasks where low profile and specific inductance values are critical for signal integrity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official Delevan resources or authorized distributors for verified cross-reference data before implementing any alternative components.
