103R-181K

Overview

The Delevan 103R-181K is a fixed inductor with an inductance of 180 nH and a tolerance of ±10%. It features a maximum DC resistance of 200 mΩ and supports a maximum current of 695 mA. The component utilizes a nonstandard, two-lead package configuration.

Feature Summary

• Unshielded construction for minimal magnetic interference
• Nonstandard two-lead package design

Applications

• RF circuit applications

Procurement Notes

Verify the specific package type against schematic requirements, as the 103R-181K uses a nonstandard two-lead configuration distinct from standard surface-mount footprints. Confirm that the 695 mA current rating meets the operational demands of the target circuit to ensure reliable performance under load conditions.

Selection Notes

Select this component when a low-inductance value near 180 nH is required for RF filtering or impedance matching. Ensure the nonstandard leaded form factor fits the available board space, as it differs from common SMD packages like 0402 or 0603 used in other series.

Part Context

This part belongs to the Delevan 103R series, which specializes in unshielded RF inductors. Unlike the shielded P1812R or SP1812R series, this series prioritizes high-frequency performance with lower parasitic effects, suitable for demanding RF environments.

Replacement Considerations

Direct substitutes include the 103-181K variant from the same manufacturer family.
