    Hi Wei,

    Here are the parameters for a 3rd-order Foster network following the format below. This should be sufficient for the customer (I am having a small issue with the 4th-order). If they have to have a fourth order circuit, let me know and I'll get it fixed.

    R1 = 0.20759, R2 = 0.0028637, R3 = 0.022834

    C1 = 0.27484, C2 = 0.0012515, C3 = 0.033355

    Here is a comparison between the CAB006M12GM3 Zth data and the 3rd order fit for the above parameters.

    Thanks,

    I was able to figure it out. Here is the 4th order.

    R1 = 0.0018372, R2 = 0.031065, R3 = 0.0082913, R4 = 0.19263

    C1 = 0.00084193, C2 = 0.12324, C3 = 0.016418, C4 = 0.35435
