108R-273GS

Overview

The Delevan 108R-273GS is a fixed surface-mount inductor with an inductance of 27 µH and a tolerance of ±5%. It features a maximum DC resistance of 8 Ohms and a rated current of 55 mA. The component utilizes an unshielded wirewound design on a ferrite core, housed in a non-standard package measuring 2.66 mm in length, 2.41 mm in width, and 2.41 mm in height. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Wirewound construction on a ferrite core for stable inductance
• Unshielded design suitable for general circuit applications
• Surface-mount termination for automated PCB assembly

Applications

• General-purpose signal filtering
• Power supply choke circuits
• RF impedance matching networks

Procurement Notes

Verify the active lifecycle status directly with API Delevan or authorized distributors, as availability may vary. Confirm that the non-standard package dimensions align with your PCB footprint requirements before ordering. Ensure the 55 mA current rating meets your circuit's operational demands to prevent saturation.

Selection Notes

Select this component when a 27 µH inductance value is required with low current handling capabilities. The unshielded nature necessitates careful layout planning to minimize electromagnetic interference with adjacent traces. Compare the 8 Ohm DC resistance against your voltage drop constraints to ensure efficient power delivery.

Part Context

This part belongs to the 108R series of fixed inductors from API Delevan. It shares the 27 µH nominal value with other variants like the 1008R-273J but differs significantly in physical size, current rating, and DC resistance characteristics due to its specific wirewound architecture.
