108-183G

Overview

The Delevan 108-183G is a fixed surface-mount power inductor with an inductance of 18 µH and a tolerance of ±2%. It features an unshielded design with a maximum DC resistance of 4.4 Ohms and a rated current of 75 mA. The component utilizes a ferrite core and operates within a temperature range of -55°C to 125°C. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and a maximum height of 1.91 mm.

Feature Summary

Unshielded wirewound construction for RF applications
Ferrite core material providing stable inductance
Nonstandard two-lead surface mount package

Applications

RF circuit filtering
Power supply choke applications
General-purpose signal processing

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm the specific lead configuration matches the nonstandard two-lead requirement for PCB layout compatibility. Ensure operating temperatures remain within the specified -55°C to 125°C range during deployment.

Selection Notes

Select this component when an unshielded 18 µH inductor with high DC resistance is required. Consider the 75 mA current rating against load requirements. The small footprint suits space-constrained designs, while the unshielded nature may necessitate careful placement to avoid magnetic interference.

Part Context

This part belongs to the 108 series of fixed inductors from API Delevan. It serves as a specialized passive component for electronic circuits requiring precise inductance values. The series is designed for surface-mount technology integration.
