108-333H

Overview

The Delevan 108-333H is a fixed surface-mount RF inductor with a nominal inductance of 33 µH and a tolerance of ±3%. It features a maximum DC resistance of 13 Ohms and a rated current of 45 mA. The component exhibits a self-resonant frequency of 12 MHz and a minimum Q factor of 30. Designed for non-standard SMD/SMT termination, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Fixed inductance value optimized for radio frequency applications
• Surface mount construction for automated PCB assembly
• High stability across extended industrial temperature ranges

Applications

• RF choke circuits
• Radio frequency signal filtering
• Impedance matching networks

Procurement Notes

Verify the manufacturer designation carefully, as API Delevan and Delevan are associated with this part number in public records. Confirm RoHS compliance status, as sources indicate conflicting information regarding regulatory adherence. Ensure the specific package dimensions match the target footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a precise 33 µH inductance is required for high-frequency circuitry. Consider the 13 Ohm DC resistance limit for power loss calculations. Evaluate the 45 mA current rating against peak operational loads to prevent saturation or thermal issues in the final design.

Part Context

This component belongs to the fixed inductor category, specifically designed for radio frequency environments. It serves as a passive electronic element used to block high-frequency signals while allowing direct current to pass. The non-standard package distinguishes it from common industry sizes like 1812 or 1008.

Replacement Considerations

Public documentation lists the S1008R-333K as a direct substitute. Verify that the shielded construction and different current ratings of the replacement part align with the original circuit requirements.
