It features a maximum DC resistance of 120 mOhms and supports a maximum DC current of 900 mA. The component has a minimum Q factor of 48 and operates within a temperature range of -55°C to +125°C. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded chip construction for standard RF applications
• High current handling capability up to 900 mA
• Compact rectangular SMD footprint

Applications

• RF circuit design
• General purpose inductor tasks
• Surface mount assembly

Procurement Notes

Verify the specific suffix 'MS' against official manufacturer documentation to confirm terminal plating and RoHS compliance status. Ensure the ordering part number matches the required inductance value of 33 nH and tolerance specifications before procurement. Cross-reference datasheets for exact package dimensions and thermal ratings.

Selection Notes

Select this component for applications requiring a compact 1010 footprint with high current capacity. The unshielded design suits general RF purposes where magnetic interference isolation is not critical. Verify that the 900 mA rating meets the circuit's operational requirements and that the 33 nH inductance aligns with the target frequency response.

Part Context

This component belongs to the Delevan 103R series of fixed RF inductors. These parts are designed as general-purpose surface-mount devices suitable for various electronic assemblies. The series offers standardized dimensions and electrical characteristics for integration into modern PCB layouts.

Replacement Considerations

Check for compatible substitutes such as the 103-330MS or 103R-330KS if pinout and electrical parameters match. Verify that alternative components maintain the same 33 nH inductance and current handling capabilities.
