Example: If I MAX = 8 Amps L, inductance required = 100 μHenries Required inductance L, core size, and core nominal inductance (A L) are known.ĥ.
Any core size line that intersects the LI² coordinate represents a workable core for the inductor if the core’s A L value is less than the maximum value obtained on the chart.Ĥ. This represents the smallest core size and maximum A L at which saturation will be avoided.ģ. Read the maximum nominal inductance, A L, on the Y-axis. Locate the LI² value on the Ferrite Core Selector chart below.įollow this coordinate in the intersection with the first core size curve. I = maximum DC output current + 1/2 AC RippleĢ. L = inductance required with DC bias (millihenries) Only two parameters of the design applications must be known: One can determine the smallest core size, assuming a winding factor of 50% and wire current carrying capacity of 500 circular mils per ampere. These core selection procedures simplify the design of inductors for switching regulator applications. By adding air gaps to these ferrite shapes, the cores can be used efficiently while avoiding saturation. For switching regulators, power materials are recommended because of their temperature and DC bias characteristics. For other inquiries regarding inductor design with Magnetics ferrite cores, Contact our Applications Engineers or submit a Custom Inductor Design request.įerrite E cores and pot cores offer the advantages of decreased cost and low core losses at high frequencies. The following design guide may also be downloaded as a PDF. so if you like to do it simple and easy please watch our next video to show you how you can use this kind of sites and etc.Inductor Design with Magnetics Ferrite Cores at the first time that I like to do it by myself, I was read many articles and application notes, but when I found that there is some sites that they do it in second I feel some. So watch our next video to find out how you can measure them:
Each core have 3 diameter and it's really important in designing. At the first we must know the diameter of our core. so if your frequency is higher than 1KHZ use Ferrite cores.įor introduce and more initial info of this cores we making a video that you can watch it from here: Īll of our videos time is about 22min, please watch them! it's better for your designing too.Ī toroid inductor cores have two kind of material: Ferrite(used in high frequency) & Iron powder (for low and high frequency) although there is some special material too, but they're not typical.Īnd the permeability of Ferrite cores is so higher than Iron powder and it's mean you can have bigger inductance with less wiring. Hello and welcome to Toroid inductor making room!!įirst of all I don't like to wast people time by introductions and this kind of stuff so we're going to do it.
