Upgrading an Arduino NG to Auto-Reset

I was going to upgrade my NG and was wondering if this is the right kind of cap? In this how to: http://www.arduino.cc/en/Hacking/NGAutoReset it said a "0.1uF (100 nano-farad) capacitor"

this is the one I found at radioshack....

0.1µF 50V Hi-Q Ceramic Disc Capacitor http://www.radioshack.com/product/index.jsp?productId=2062365&cp=2032058.2032230.2032267&allCount=111&fbn=Type%2FCeramic+Disc+Capacitors&f=PAD%2FProduct+Type%2FCeramic+Disc+Capacitors&fbc=1&parentPage=family

I just don't want to try this, and fry my arduino.

thanx

Yes, this one can be used.

cool, thanx.

one more thing, what about polarity?

This kind of cap has no polarity. You can solder it anyway.

thanks alot.
