Derek: You obviously are facing a challenge (a.k.a. problem).
Sometimes you actually have to make things yourself, and this may be one of those times. For the inductors, I'd say you will have to go with air core. I've done air core inductors up to the hundreds of microhenries (for LF antenna couplers) but we are talking big - 6 inch diameter by 18 inch length. I was also looking for high unloaded Q, which also influenced the size. But even with air core, you still have problems with the coil former and wire insulation. I used fiberglass, but although I haven't checked, I don't think that will work at 180C. Possibly Teflon (expensive) or maybe Delrin. For capacitors, you could go back to basics and make your own, with metal plates and dielectric. How about depleted Uranium for the plates, and Gandolinium dioxide for the dielectric? -( ;) Jack Jacob Z.
