108R-333K

Overview

The Delevan 108R-333K is a fixed power inductor featuring an unshielded design with a ferrite core. It provides an inductance of 33 µH with a tolerance of ±10%. The component supports a maximum DC current of 45 mA and has a maximum DC resistance of 13 Ohms. It operates within a temperature range of -55°C to +125°C and utilizes a nonstandard two-lead package for PCB mounting.

Feature Summary

• Unshielded construction utilizing a ferrite core material
• Fixed inductance value of 33 µH with standard tolerance
• Designed for surface or through-hole PCB integration via two leads

Applications

• General power filtering circuits
• Signal line chokes
• DC-DC converter input/output stages

Procurement Notes

Verify the specific lead configuration and physical dimensions against the official datasheet, as the package is classified as nonstandard. Confirm RoHS compliance status and manufacturing origin prior to ordering, as these details may vary by production batch and require direct validation from the manufacturer's documentation.

Selection Notes

Select this component when a compact, unshielded inductor is required for low-current applications up to 45 mA. Ensure the circuit design accommodates the relatively high DC resistance of 13 Ohms. Verify that the nonstandard lead spacing matches the target PCB footprint requirements before finalizing the design.

Part Context

This part belongs to the Delevan fixed inductor portfolio, specifically designed for power and signal conditioning. It serves as a passive energy storage element in electronic circuits, offering reliable performance in space-constrained designs where shielding is not strictly mandated.

Replacement Considerations

S1008-333K is listed as a direct substitute option.
