Overview

The Coilcraft 1812PS-332KLC is a semi-shielded surface-mount power inductor designed for efficient energy storage and filtering in DC-DC converters and power supply circuits. Its 3.3 µH inductance and 2.3 A maximum DC current rating make it suitable for moderate power applications. A critical design consideration for this component is the trade-off between its saturation current (1.4 A) and its DC resistance (90 mΩ); exceeding the saturation current can lead to significant inductance drop, impacting filter performance, while a lower DC resistance is desirable for minimizing power loss and thermal stress.

Key Features
