103R-330M

Overview

The Delevan 103R-330M is a fixed surface-mount RF inductor with an inductance of 33 nH and a tolerance of ±20%. It features a maximum DC resistance of 120 mΩ and a rated current of 900 mA. The component utilizes an unshielded design with phenolic core material, measuring 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded chip inductor construction for minimal magnetic interference
• Phenolic core material suitable for general-purpose RF applications
• Surface mount package optimized for automated assembly processes

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF inductors

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by different entities. Confirm RoHS compliance status against the latest datasheet revision. Ensure the unshielded configuration aligns with your PCB layout requirements to prevent unintended coupling. Validate that the 900 mA current rating meets your circuit's peak operational demands without saturation.

Selection Notes

Select this component when a low-inductance value near 33 nH is required for high-frequency signal paths. The unshielded design necessitates careful placement relative to sensitive traces to avoid crosstalk. Consider the 120 mΩ DC resistance impact on power loss in series configurations. Verify that the 2.54 x 2.54 mm footprint matches your board space constraints.

Part Context

This part belongs to the 103R series of fixed inductors from Delevan, designed specifically for radio frequency applications. The series offers various inductance values tailored for SMD mounting. The 103R-330M represents a specific low-inductance variant within this lineup, distinguished by its unshielded architecture and phenolic core composition.

Replacement Considerations

Direct substitutes include other 33 nH unshielded SMD inductors with similar current ratings and dimensions. Verify pin compatibility and thermal characteristics before substitution. Cross-reference with API Delevan documentation for any updated series replacements or obsolescence notices.
