105R-181G

Overview

The Delevan 105R-181G is a fixed surface-mount RF inductor with an inductance of 180 nH and a tolerance of ±2%. It features a maximum DC resistance of 190 mΩ and a current rating of 710 mA. The component utilizes a nonstandard two-lead package design, distinguishing it from typical chip-style SMD inductors. This configuration supports PCB mounting for radio frequency applications requiring specific form factors.

Feature Summary

• Nonstandard two-lead surface mount construction
• High current handling capability up to 710 mA
• Low DC resistance for efficient signal transmission
• Fixed inductance value suitable for RF circuits

Applications

• Radio frequency circuit integration
• Signal filtering in communication devices
• Impedance matching networks
• RF choke applications

Procurement Notes

Verify the physical package type carefully, as the 105R series utilizes a nonstandard two-lead configuration rather than a standard rectangular chip footprint. Confirm that the PCB layout supports this specific lead arrangement. Ensure the selected variant matches the required 180 nH specification and 710 mA current rating for the target application.

Selection Notes

Select this component when a nonstandard two-lead SMD form factor is required for RF designs. Consider the 190 mΩ DC resistance and 710 mA current limit against circuit requirements. Compare with standard chip inductors if space constraints allow, noting that this part offers a distinct mechanical profile for specialized mounting needs.

Part Context

The 105R series represents a distinct line of Delevan fixed inductors characterized by their unique two-lead surface mount packaging. Unlike common chip-style components, these parts are designed for specific mechanical integration scenarios within RF systems. The 181G suffix indicates the 180 nH inductance value with a tight 2% tolerance.

Replacement Considerations

Direct substitutes must match the 180 nH inductance, 710 mA current rating, and the specific nonstandard two-lead package geometry. Standard chip inductors may not fit mechanically without PCB redesign. Verify equivalent electrical parameters and thermal characteristics before cross-referencing.
