Very useful information.
I'm actually surprised at how well google translate worked on this page - it's completely readable..
К75 capacitors may be very very different. For example, K50-63 are made of paper & foil,
K75-93 are metalized film impregnated, and so on.
K50-10 are metalized, but made for high currents in pulse regimes. AC rating is given for 50 Hz.
Tangent of angle of losses is 0,008
24 gigaOhm insulation.
Just for information,
Do these capacitors contain PCB?
