Understanding Specifications
Abstract: inductor RMS current (A) BMAX = saturation limited flux density (T) (power ferrites like N27 or N67 have , calculated from the winding cross section and core cross section. For example, the ETD29 core with ferrite material N27 from EPCOS has a winding cross section of 97 mm2 and a core cross section of 71 mm 2. Maximum flux density for the N27 is 0.3 T. Equation 37 AP = A N A MIN AN = winding cross section (mm2 , the inductance factor AL, which depends on air gap, in the product datasheets.
