From http://www.enjoythemusic.com/diy/1108/capacitor1.htmEpcos (Siemens Matsushita)MKV B25834 polypropylene in oil capacitorEpcos was founded by Siemens Matsushita, who sold all its interests in 2006. MKV B25834 is a polypropylene in oil cap like the Siemens MKV radial capacitor talked about previously. Mundorf silver/oil also happens to be polypropylene in oil, so it was not a great surprise that Epcos sounded somewhat similar to Mundorf silver/oil when directly substituted in Mundorf's place. Not that they sounded the same, mind you, but both shared a sense of liquidity and grace, which helped music just flow effortlessly. Compared to silver/oil, Epcos had a bit more richness to voices and even more apparent smoothness in the upper-midrange region, but it conceded some sheer resolution and attack. Silver/oil sounded more like a "modern" film capacitor while Epcos leaned more in the direction of paper-in-oil caps without overt darkness or lack of resolution. I was especially glad to observe Epcos not to possess overly rounded or slow bass like some paper-in-oils can. The Epcos, not surprisingly, sounds VERY much like the Siemens MKV polypropylene in oil capacitor I described earlier. Both sound balanced, if not extraordinarily extended or obviously "airy" up top. Human voices have fluidity, richness, and sparkling liveliness that's so endearing. If you are a die-hard Teflon or polystyrene fan, you will likely call these poly oil caps a bit slower and not as lit-up, but the fans of the poly oils will call it the opposite. A great strategy is to use the Epcos with something like Russian K72 Teflon cap somewhere else in the component. K72's enthusiastic, bold, slightly upper-midrange-centric sound signature complements the ease of Epcos very well while lending the whole package a dollop of Teflon resolution. This combo sounds mighty nice, and I must thank "dweekie" for pointing me to these Epcos capacitors.

Mounting
If the vibration stress is ≤ 5 g and the capacitors are ≤ 60 mm in diameter and
160 mm in height, the bolt is used for mounting.
Grounding
Mounting bolts for grounding in accordance with VDE 0100
Grounding identification in accordance with DIN 40 011
Overpressure disconnector (mechanical)
When the overpressure disconnector responds, the capacitor extends by up to 8 mm.
So leave sufficient space above the terminals when mounting the capacitor.
