Capacitor Type Question

[Harry Muscle]

I'm building a temperature controller I found at
http://ourworld.compuserve.com/homepages/Bill_Bowden/page2.htm (scroll down
to the "Electronic Thermostat and Relay Circuit" heading) and since I still
don't fully comprehend everything about capacitors, could someone verify for
me what type of capacitor I should be using for the 22uF cap in that
circuit. I'm guessing aluminum electrolytic, but I'm not sure.

Thanks,
Harry

I would use a tantalium, but elolytic is okay too

If I go with tantalium, do I still go with 22uF? Or does the different type
affect the value to use?

Thanks,

No, the value is still the same ... type doesn't matter

An aluminum electrolytic will do fine. Something in a 6.3 to 15 volt
rating would be quite small and cheap.
