Inductor Sizing

Most of our larger inductor applications involve forced air cooling. The size and weight are determined by the effective air flow, air ambient, altitude, temperature rise, and losses due to low and high frequency currents and voltage levels. Below are curves showing the ranges we have seen in our custom designs for our customers utilizing ducted coils:

Volume Vs. LI

Weight Vs LI

For non-ducted coil designs, volume and weight will increase. For units relying on natural convection, volume and weight increase further. Liquid cooled units offer the smallest volume and weight. Precision engineers work with you to optimize a unit to meet your product size, weight, cost and performance goals.
