105R-182K

Overview

The Delevan 105R-182K is a fixed micro chip inductor designed for surface-mount applications. It features an inductance of 1.8 µH with a tolerance of ±10%. The component supports a maximum DC current of 250 mA and exhibits a maximum DC resistance of 1.5 Ohms. Constructed as an unshielded device, it utilizes a nonstandard two-lead configuration suitable for PCB mounting. This power inductor belongs to the Micro i Chip Inductors series manufactured by API Delevan.

Feature Summary

• Unshielded wirewound construction for specific electromagnetic interference requirements
• Two-lead nonstandard package design enabling flexible board layout integration
• Ferrite core material providing stable inductance characteristics

Applications

• General power supply filtering circuits
• DC-DC converter input or output stages
• Signal conditioning networks requiring low current handling

Procurement Notes

Verify component authenticity through authorized API Delevan distributors. Confirm RoHS compliance status via official datasheets before integration. Ensure storage conditions maintain lead integrity. Validate part markings against manufacturer specifications to prevent counterfeit substitution during assembly processes.

Selection Notes

Select this component when unshielded topology is required to minimize magnetic coupling effects. The 1.5 Ohm resistance suits low-current applications where voltage drop is acceptable. Consider the nonstandard footprint constraints during PCB layout phase. Evaluate thermal dissipation capabilities relative to the 250 mA continuous current rating.
