Power Inductors


Power inductors typically need to support a ripple current AND support a high peak current without saturating. With switch mode power supply frequencies moving upward every year, the demands on inductors are starting to outpace conventional wire wound technologies. That’s why we maintain an active R and D effort focused on switch mode power supply magnetics. With three patents and 1000’s of power inductors currently in use, we are recognized as an industry leader for best in class engineering solutions for this important component. Talk to our highly capable designers about any of your power inductor requirements. More info about our power inductors.
