108-333G

Overview

The Delevan 108-333G is a surface-mount RF inductor with a nominal inductance of 33 µH and a tolerance of ±2%. It features an unshielded wirewound construction designed for PCB mounting. The component has a maximum DC resistance of 13 Ohms and supports a maximum DC current of 45 mA. Key electrical characteristics include a minimum Q factor of 30 and a self-resonant frequency of 12 MHz. The physical dimensions are non-standard, measuring approximately 3.94 mm in length, 2.79 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded wirewound design suitable for RF applications
• High precision inductance with ±2% tolerance
• Standard SMD/SMT termination style

Applications

• RF circuit filtering
• Impedance matching networks
• General RF signal processing

Procurement Notes

Verify the active status and availability directly with authorized distributors or the manufacturer API Delevan. Confirm that the specific package type matches your manufacturing requirements. Ensure compliance with relevant environmental regulations if applicable to your region. Request updated documentation to confirm any recent product changes or notifications before finalizing procurement orders.

Selection Notes

Select this component when a high-inductance value of 33 µH is required in a compact surface-mount form factor. Consider the low current rating of 45 mA and the relatively high DC resistance of 13 Ohms during circuit design. The unshielded nature may require careful layout consideration to minimize electromagnetic interference with adjacent components.

Part Context

This part belongs to the broader category of fixed RF inductors manufactured by API Delevan. It is specifically designed for surface-mount technology (SMT) assembly processes. The component serves as a passive electronic element used primarily in radio frequency circuits where precise inductive reactance is necessary for signal conditioning and filtering tasks.

Replacement Considerations

Direct substitutes include the 108R-333G variant from the same manufacturer family. Other potential replacements must match the 33 µH inductance, similar current ratings, and compatible physical footprint to ensure proper integration into existing designs without requiring board modifications.
