I don't know what model it was in, and that is sort of moot because it was used in a custom design audio low pass filter that was not an H product. <SPAN style="FONT-SIZE: 18pt">My guess is that it is in the 150-180 microhenry range, or at least that looks like it is what it could have been by my modeling. Thanks and 73. </SPAN>
