Hi Demitris, I am not sure of the types codes but I used 1000v or greater rating, the problem often is that the caps are not rated for high pulse currents. The best kind of caps that are used are rat

Hi Alan, I am also using a simulator, the free LTSPICE which seems to work OK, in fact I use it with wine under linux. With this, it is easy to predict the voltages that will develop across all compo

Hi Alan, thanks for the tip, I will keep an eye open for RIFA PHE428 or PHE450 which seems to be the newer version of that capacitor type. In my PA, I used two .1 uF caps in series to make .05 uF, th

Hi Dimitrios, yes those should do the job. I suppose that you need a situation with paralleled caps where any one can carry the peak current. It is probably a bit marginal if you really have to rely

Hi Dimitris, LF, here is a bunch of 33 nF / 2 kV FKPs working in my indoor LF transmit loop experiment: http://df6nm.bplaced.net/LF/Indoor_Loop/indoor_loop_matching.jpg With 200 W TX power, the total
