| "over current" use of a Pulse transformer - ( or an alternative ) |
| << < (6/10) > >> |
| T3sl4co1l:
One would hope, the transformer is designed with nominal imbalance in mind. This does however limit the average permeability, which means more core size and wire length are more limited (larger). Tim |

Yes, one would hope so. I've contacted TDK and hope they will come back with some more info. |

That's why you never shall exceed current specs of transformer and whole discussion about "over current" use of a Pulse transformer ends with such conclusion. --- End quote --- Ogden, we'll see what happens. You nor i actually know the characterisistics of this transformer for operating outside the rated limits. ( i assume you hav'nt tested it, in this situation, but if you have, i'd be all ears ). For me, its well worth pursuing this. If it works i'll be very happy. If it does'tn i've not lost a lot. |
| T3sl4co1l:
Nice thing is because it's intended to be a bias tee, you can intentionally unbalance it in a test, run some current through it, and measure the saturation flux on the free winding(s)! Just gotta order up some parts and put 'em to the function generator and scope. Tim |

I do not know particular transformer indeed, --- End quote --- Your not making any sense. You say i fail miserably, with my assumption. ( which was that you dont' know about this specific transformer ), then you go on to say you dont' know this particular transformer in the very next sentence. You need to live outside the datasheets a little, life is much more exciting and interesting there. :-) |
