I'm about to buy some capacitors for a SSTC or DRSSTC and I'm not sure if the capacitors with the below specifications are fit for SSTC or DRSSTC use. What do you think?
High Voltage Polypropylene Film Capacitor Type: PPS [CBB81] Capacitance: 0.33uF Rated voltage: 2000V Capacitance tolerance: ±5% Dimension: 25mm in width and 29mm in height
Please guys, in a power supply for PC is some kind of that condensators - that round blue and big "poppa" brown - plz tell me it is good enough and i finally found capacitors for 2K(ilo)V(olts), and plz. tell me if it is good capacity (and what hell is that capacity) to run some SGTC (verry little certainly)! You´ll make me very happy !!! THat big poppa is looking like those on the picture above
And this yellow square one - should it be applied for MMC ? it is rated to 280V(0,22uF), but dunno nothing more ...

For tesla coil use I believe many would recommend 1kv+ so the big daddy brown one most likely will not work, the yellow one won't work either I've tried it died (internal flash over at low voltages but high peak surges (looked cool) but don't work) the Blue 2Kv cap...I'm not sure.

the blue one definetly won't work because it's a ceramic cap. It will have very little capacitance and will flash over or pop and fling little ceramic bits.

too be perfectly honest with you, very few kinds of MMCs will take strong pulse discharges. The capacitors that survive this kind of abuse are double wound --
