    I'm building a temperature controller I found at (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.

  2. 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?

  4. No, the value is still the same ... type doesn't matter
  5. An aluminum electrolytic will do fine. Something in a 6.3 to 15 volt
    rating would be quite small and cheap.
