LP2618MT3R3

Fixed Inductors Overview

The LP2618MT3R3 is a general purpose power inductor manufactured by Stackpole Electronics Inc. It features a rectangular construction with a ceramic base and gold-plating, distinguishing it from LCP plastic variants in the series. The component has a nominal inductance of 3.3 µH and a maximum rated current of 4.5 A. Its DC resistance is specified at 0.017 Ω. Operating within a temperature range of -40 °C to 125 °C, it utilizes an SMT package measuring 6.6 mm in length, 4.45 mm in width, and 2.92 mm in height.

Fixed Inductors Feature Summary

• Utilizes a ceramic base with gold-plating for enhanced performance compared to standard LCP plastic bases.

Fixed Inductors Applications

• Power supply circuits

Fixed Inductors Procurement Notes

Verify the specific datasheet version for the LP2618MT3R3 to confirm electrical tolerances and thermal characteristics. Ensure compatibility with automated pick-and-place equipment due to the SMT form factor. Cross-reference the manufacturer's official documentation for any updates regarding material compliance or RoHS status prior to finalizing procurement specifications.

Fixed Inductors Selection Notes

Select this component when high saturation current and low DC resistance are required in a compact surface-mount footprint. The ceramic base construction offers distinct advantages over plastic-based alternatives in the same series. Evaluate thermal management requirements against the 125 °C maximum operating temperature limit during circuit design.

Fixed Inductors Part Context

This part belongs to the LP2618 series of general purpose inductors produced by Stackpole Electronics Inc. The series includes various inductance values sharing the same physical dimensions and mounting style. The LP2618 designation indicates the specific case size and construction type used across the product line.

Fixed Inductors Replacement Considerations

Direct substitutes include other parts within the LP2618 series with matching inductance and current ratings. Verify that alternative components utilize the ceramic base if gold-plating benefits are critical to the application.
