Overview

The Coilcraft 1812PS-222KLB is a semi-shielded, wirewound surface-mount power inductor designed for high-current applications. Its primary function is to store energy in magnetic fields, smoothing current ripple and filtering noise in DC-DC converters and power supply circuits. A critical design consideration is the trade-off between saturation current and DC resistance; while a lower DC resistance (70 mOhms) is desirable for efficiency, it can limit the maximum current handling capability before magnetic saturation occurs, impacting performance in demanding power delivery scenarios.

Key Features

Inductance: 2.2 µH
Maximum DC Current: 2.4 A
Saturation Current: 1.7 A
Maximum DC Resistance: 70 mOhms
Package: 1812 (4.53 x 3.20 mm)
Operating Temperature Range: -40°C to +105°C

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Buck converter output filtering for mobile device power management
Input current smoothing in automotive power systems
EMI suppression in switch-mode power supplies
Energy storage for transient load demands in industrial controls
