Dear Daniel
For that money you will get a 2.61nF MMC.
Why?
Your peak voltage is 14142V
Your MMC should be rated at a littlebit higher, lets say Peak voltage
+ 10% = 17677V
Your capacitor is rated at 1000V, this means 18 capacitors in series
will give you a 18000V MMC
18 x 1.19$ = 21.42$
18 x 47nF in series is a capacitance of 2.61nF
What you need is:
LTR value based on 110V/60Hz
9.15nF for a ssg
17.08nF for a rsg
This means:
If your only option 47nF is you can make 3 of those strings to get
7.83nF, this for a price of 64.26$
Or you make 4 strings to get a capacitance of 10.44nF for a price of 85.68$
Im afraid you won't get there with 30$
Kind regards,
Sebastiaan
