Applications requiring low EMI in a small package will benefit from the PTI powdered-iron toroidal inductors. With height ranges from 0.55" to 1.6", the pcb-mount inductors can be utilized for SMPS operations, EMI filters, output chokes, and energy storage devices. The devices feature air gaps that are inherently distributed in the powdered iron core. These air gaps reduce material permeability and increase the energy storage capabilities, resulting in smaller size inductors. The inductors are designed for a 30° temperature rise in still air when loaded to rated dc current at 40 kHz.
