Look at this chematic:
**broken link removed**

The 10uF and the 1uF capacitor is electrolytt like this:
**broken link removed**
Right?

But what kind is the last one (the 0,1uF one)
 

0.1 uF ceramic capacitors are a small disk about 1/4 inch (6 mm) diameter. depending on the rated voltage they could be bigger. Usually are marked as 104.
 

zanor, C2 could be electrolitic polarized capacitors, but C3 not necesarily, C1 of 0,1uF seems to be a non polarized one, any kind is good.
C1 and C2 are to storage energy.
C3 is to reduce noise.
 

Hello,
Yes, you are correct, the 10 uF and 1uF are both electrolytics, and albert22 is also correct on the third one. It is in fact a small ceramic, and the value written on it will be 104. The first two numbers are the value in pF and the third number is the multiplier (number of zeros.) So the value 10000 pF is the same as 100nF or .1uF. A cap marked 103 has a value of 10 nF, or .01 uF. Generally ceramics larger than about 220 nF are hard to find. The clue about electolytics is given by the symbol; one plate is black, the other white.
You also have to watch out for the voltage value. Normally you want to specify caps that are rated for at least 2 times the amount of voltage they will see. So if your transformer puts out 24 volts at the secondary, you would want to use caps rated at 48 volts.

Robert
 

C1 is ceremic capacitor
C2 and C3 are Electrolytic
 

First one(Picture) is the electrolytic Capacitor thay are Polar
while in Schematic they are non polar Capacitors
they often used to decrease the attenuation they are off Ceramic or Polyester
