SD3110-1R5-R

Fixed Inductors Overview

The SD3110-1R5-R is a discontinued surface-mount power inductor from Eaton Electronics, part of the SD3110 series. It features a shielded drum core design with an inductance of 1.5 µH and a tolerance of ±30%. The component has a maximum DC current rating of 990 mA and a maximum DC resistance of 103 mΩ. Its compact dimensions are 3.1 mm in length, 3.1 mm in width, and 1 mm in height. The device utilizes standard SMD/SMT termination for PCB mounting.

Fixed Inductors Feature Summary

• Shielded drum core construction to minimize electromagnetic interference
• Compact surface-mount footprint suitable for space-constrained designs
• High saturation current capability relative to physical size

Fixed Inductors Applications

• DC-DC converter output filtering
• Power supply input stages
• General-purpose power circuit energy storage

Fixed Inductors Procurement Notes

This component is officially discontinued by Eaton Electronics. Verify availability through secondary market distributors or consider immediate substitution. Confirm end-of-life documentation and final purchase dates if sourcing remaining stock. Ensure compatibility with existing PCB layouts before procurement.

Fixed Inductors Selection Notes

Select this component only if legacy board compatibility is mandatory. Evaluate thermal performance under load conditions given the 103 mΩ resistance. Compare against newer Eaton series for improved efficiency and availability. Verify that the 990 mA current rating meets system peak requirements without saturation.

Fixed Inductors Part Context

The SD3110 series represents Eaton's metalized shielded drum core power inductors designed for high-density applications. This specific model belongs to a family of fixed inductors optimized for power management circuits. The series was widely used in consumer electronics and industrial power supplies before discontinuation.

Fixed Inductors Replacement Considerations

Consult the SD3114 data sheet as the recommended alternate replacement. Verify pinout compatibility and electrical parameter alignment before substitution.
