Boutique caps in oil... reliable?

Hi Everyone,

Just kind of openly curious.  On occasion I will read a post here or there that a boutique film cap which uses oil as a dielectric has leaked (i.e. failed). 

Just wondering when it comes to these high end oil impregnated (or maybe even wax!) caps what your experience has been with long term reliability.

 

Thanks!

Thanks for your perspective. My current needs are as line level high pass filters, so even if there was DC leakage I don’t think I’d care.

I’m a little curious though, is oil-filled the same as oil impregnated?

When I think of oil-filled, I think of big cans from the old days.

Thanks for the recommendations. The complexity for me is not the high pass filter. It’s a circuit that works on the AVR’s 12V trigger and lets me integrate the sub into both the Anthem AVR and Luxman Integrated.  I think I pretty much have it figured out, but need to shop for nice sounding caps to use.

Well my applications are in speaker crossovers as well as line level high pass filters.

Right now I am prototyping a little switch that will let me:

  1. Switch my HT preamp outs to my Luxman without my need to use the Luxman’s bypass switch
  2. High pass all signals to the Luxman amp
  3. Provide sub outs

The idea being to integrate my HT and subwoofer seamlessly with my 2 channel system. :) I will need 0.047 caps, relatively physically small so no Coke can sized caps here! :D
