The definition of rated current continues to vary between passive component manufacturers in the power electronics industry, despite the adoption of IEC standard 62024-2 which specifically describes how rated current should be measured. Because of this, misconceptions can still arise about what this parameter actually represents and how design engineers can use it.
With this in mind, Würth Elektronik has developed a thermal model which calculates the rated current of power inductors given specific trace dimension on a PCB. This will give design and component engineers the ability to explore how the rated current of parts is affected by different conductor dimensions used on the PCB.
