ASC X386S capacitors



ASC Oil-Filled Polypropylene: Excellent for high voltage power supply applications.
These are non-inductively wound, metallized non-polar polypropylene, Spearinol III oil filled aluminum cans. Operating temperature to +70°C.

ASC's design includes a partial impregnation technique utilizing a non-toxic natural oil based coolant that avoids the problems of swelling and premature failure which can occur with polypropylene films immersed in more commonly used synthetic hydrocarbon and petroleum based oils.


According to "The Tempo Electric Cap Test", these are the best capacitors for power supplies.

If space allows, this capacitor-in-a-can is superior to any electrolytic on the market, Period. This includes Black Gate, Nichicon, or Panasonic.
For curiosity, we tried a 2.0uF ASC X386 in the signal path, but ended the experiment after 30 seconds. Keep them in the power supply section, especially of amplifiers, where they belong. Though there is a point of diminishing returns, the higher the value, the tighter and deeper the bass will be. Even ones with 10% rated tolerance measured within 1%. Also sold under the Angela Instruments brand. Primarily rated for use with AC, they can be used in DC applications, as well. Curiously, they did not perform as well when used as AC line filters (see below). Downside: Large size, awkward mounting
