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.

Toroidal Power Inductor

This 1 mH, 8 amp powdered core toroidal inductor is ideal for buck boost applications at power levels up to 10 kW, and frequencies up to 250 kHz. With a soft roll off of L vs. Ipk, very low EMI and low distributed capacitance, this inductor is suitable for applications with up to 10% peak to peak ripple. Different core options and winding options are available depending on the specific design objectives.
