Hello, I am building a small power factor correction device using Arduino to control gating signals. But the real problem is I can't find parts to finish my prototype, so I thought I'd just pop on and ask if anyone knew where I could find 200uF caps rated for 220Vac @ 60Hz? Thanks all.
Here's one:
--
The Gadget Shield: accelerometer, RGB LED, IR transmit/receive, speaker, microphone, light sensor, potentiometer, pushbuttons
You can't put AC through that it will explode.
Non polarised capacitors of that sort of value are very big and very expensive.
I was assuming he'd be using it for rectified DC so ~315VDC.
If indeed he needs a cap for AC then I believe he can put two back to back to effectively get a nonpolarized capacitor (at half the capacity, so a bigger capacitor would be needed). Not sure what is needed in his application though.

The Quick Shield: breakout all 28 pins to quick-connect terminals
If it is power factor correction like he said then it has to be mains and if you put two of those back to back I am sure the ripple current will blow the thing up anyway.
If it's mains then why does it have to be 200uF??

The DIN Rail Mount kit for Arduino: quickly attach your Arduino to standard DIN rail
Because that is the only reason to use power factor correction at these voltages.
Anyway power factor correction only makes you pay more money to the power companies, it serves no other purpose.
I am having a very hard time finding some capacitors that I need as ... the big question is - is it polarized or not? you can use non-polarized ...
