  8. AN738 Vishay Siliconix Document Number: 71923 01-Oct-02 www.vishay.com 3 where Ac is the effective cross-section of the core. In this case Lp(max) = 64.6 mH, Ipk =0.73A, Ac =0.32cm2, Bm = 0.15 gives a minimum air gap of 60.2mm. The closest “off-the-shelf” core gap for this RM6 core was 110mm. Once the minimum air gap has been determined ...
