RE: [TCML] MO Capacitors

["andrew" <andrew@xxxxxxxxxxxxxxxxxxxxx>]

Many thanks for replys re MO caps.
I see they are used a bit in level shifter psu's sometimes.
As for me, I am leaning back towards an mmc. I was just a bit reluctant to
spend $NZ 200
to build one if I didn't need to!
Cheers
Andrew

Not what you want.


Too much capacitance, designed as a DC filter capacitor (at line frequency,
50-60 Hz) and has very high loss at the several hundred kHz in a tesla coil.
