Re: [TCML] caps
Thanks for the details on the dielectric fluid.
Another thing to add to the information store!

Dave and Randy,
The 1945 article covers many advantages of Lectronol in high frequency
induction heating capacitors, but unfortunately it does not provide
any details about WHAT Lectronol actually is. However, I was able to
find another paper that does discuss Lectronol. The good news is that
Lectronol is NOT one of the many PCB's used in capacitors. Instead, it
is a colorless liquid "obtained from dibutyl ether and sebacic acid
The above nugget was found in a 323pp paper that discusses Lectronol
and many other dielectric fluids as well. The paper is "Electric
Strength of Liquid Dielectrics" by I Balygin. This is available as a
free download at the Defense Technical Information Center (DTIC):
Other than being comparatively large for their voltage and capacitance
ratings versus capacitors using more modern technologies, your caps
should work fine in TC use. And, because the fluid is essentially THE
dielectric, they may also be self-healing to some degree.
