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
