108R-183GS

Overview

The Delevan 108R-183GS is a fixed surface-mount inductor with an inductance of 18 µH and a tolerance of ±2%. It features a maximum DC resistance of 4.4 Ohms and a rated current of 75 mA. The component utilizes an iron core and is unshielded, housed in a nonstandard two-lead SMD package measuring 2.54 mm x 2.54 mm with a maximum height of 1.91 mm. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded wirewound construction for RF applications
• Iron core material providing stable inductance characteristics
• Compact nonstandard two-lead surface mount footprint

Applications

• RF circuit filtering
• Signal processing networks
• General purpose fixed inductance requirements

Procurement Notes

Verify RoHS compliance status as sources indicate conflicting information regarding regulatory adherence. Confirm the specific suffix designation matches the required lead finish and packaging format. Ensure the manufacturer's datasheet is consulted for precise mechanical tolerances and soldering profiles before integration into production designs.

Selection Notes

Select this component when an unshielded 18 µH inductor with low current handling is required. The 4.4 Ohm DC resistance limits suitability for high-current power paths. Verify that the nonstandard package dimensions fit the target PCB layout constraints compared to standard metric sizes.

Part Context

This part belongs to the 108R series of fixed inductors manufactured by API Delevan. The series typically offers various inductance values in a compact form factor suitable for space-constrained electronic assemblies. The 108R-183GS specifically denotes the 18 µH variant with GS suffix indicating specific packaging or compliance attributes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 18 µH value, 75 mA rating, 4.4 Ohm DCR, and physical package dimensions.
