108-273G

Overview

The Delevan 108-273G is a fixed surface-mount RF inductor with an inductance of 27 µH and a tolerance of ±5%. It features a maximum DC current rating of 55 mA and a maximum DC resistance of 8 Ohms. The component utilizes an unshielded design with a nonstandard package footprint, suitable for PCB mounting. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded surface-mount construction
• High stability across wide temperature ranges
• Compact nonstandard form factor

Applications

• RF circuit filtering
• Signal processing networks
• General purpose inductive applications

Procurement Notes

Verify the exact suffix designation (G vs K) against official datasheets, as variations may indicate differences in tolerance or lead finish. Confirm RoHS compliance status directly with the manufacturer, as legacy API Delevan components often require specific environmental verification. Ensure the nonstandard package dimensions align with the target PCB layout before procurement.

Selection Notes

Select this component for applications requiring precise 27 µH inductance in space-constrained designs. The unshielded nature requires careful placement to minimize electromagnetic interference with adjacent traces. Verify that the 55 mA current limit meets the operational requirements of the specific circuit node.

Part Context

This part belongs to the 108R series of fixed inductors manufactured by API Delevan. The series is characterized by small, nonstandard SMD packages designed for high-frequency applications. The 108-273G specifically represents the 27 µH variant within this lineup, offering a balance of inductance and current handling for RF tasks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the nonstandard package and specific electrical characteristics, direct pin-to-pin replacements from other manufacturers may require schematic and layout modifications.
