105R-272G

Overview

The Delevan 105R-272G is a fixed surface-mount inductor from the 105R series. It features an unshielded design with an iron core, providing an inductance of 2.7 µH and a tolerance of ±2%. The component has a maximum DC resistance of 2 Ohms and a current rating of 220 mA. It utilizes a non-standard two-lead SMD package configuration suitable for general-purpose applications.

Feature Summary

• Unshielded construction utilizing an iron core material
• Fixed inductance value with tight manufacturing tolerance
• Surface-mount form factor with two leads

Applications

• General purpose signal processing circuits
• RF filter networks
• Power supply filtering stages

Procurement Notes

Verify the specific manufacturer designation API Delevan Inc. when sourcing. Confirm the unshielded topology and iron core composition match circuit requirements. Ensure the 220 mA current rating and 2 Ohm DCR are within system limits. Check for RoHS compliance status as historical data may vary by production batch.

Selection Notes

Select this component for applications requiring a compact unshielded inductor with precise 2.7 µH values. The iron core offers stability, while the unshielded nature requires careful PCB layout to minimize electromagnetic interference coupling. Verify that the 220 mA rating supports peak load currents without saturation issues.
