Hello, I was browsing around and found statistics that stated breadboards are generally rated for 10khz and below. I am trying to use a breadboard for a ZVS flyback driver. Does anyone have any real information for solderless breadboard specs???

I would be more worried about the currents you're going to drive through those contacts than the switching frequency being too high.

Spot the breadboard? That's 300W at 4MHz.

How the.....I've melted the holes on my boards with as little as 150W at just a few kHz. Is there anything Richie can't do? (though, to be fair, those blue ones look a bit heftier than the radioshanty breadboards)
