Hello! I'm a bit off a newbie and can someone help me pick out parts for this amplifier?

I don't need the 50K potentiometer.

 

What? All the parts are labeled. The only thing left to the imagination is that the capacitors should be rated for at least 16 volts and what country you are in.

Should i use aluminium or ceramic capacitors?

 

Where did you get that schematic?
It doesn't correspond to the data sheet I found.

I found it here: http://www.circuitdiagram.org/1w-mini-stereo-amplifier-tda2822m.html

Yes. The big ones are aluminum and the small ones are ceramic.
Another way to say this is, Try buying a 100 uf ceramic capacitor or try buying an aluminum 0.1 uf capacitor. Not likely you can do that.

Oki tnx.

 

That schematic is incorrect. Look at this data sheet (compare the output capacitor values).

Okay thank you!

 

(compare the output capacitor values).

you don't think there is a different?

Crutschow just named the difference.
and the M only describes the plastic DIP package.

 

Hello,

The difference between the TDA2822 and TDA2822M is that the TDA2822 is 16 pins and the TDA2822M is 8 pins.
There is even a TDA2822D wich is in a SO8 housing.
See the both attached datasheets to compare them.

Can i help finding a 470uF capacitors that are not either higher than 5MM or has a diameter of 5MM

 

Hello,

Where are you located?
That way we can perhaps give you localized advice.

I live in Norway.

 

Hello,

Where do you normaly get your parts?
The smallest diameter I can find for a 470 μF / 16 Volts capacitor is 8 mm.

I normaly get them at http://www.digikey.com/ If it is not smaller then 5 mm it will not fit.

Is there any other solution instead of one 470uF?

 

Hello,

Looking at Digikey, I see a minimum diameter of 8 mm or a minimum height of 7.7 mm.
I think you are out of luck with your size restrictions.

You could use 5 X 100 μF / 16 V capacitors parallel.
That will take more space but less height.

Yeah, Is there any other solution instead of one 470uF? Or is there another amplifier instead of 2822M where i don't need as big capasitors?

 

The capacitors are dictated by the speaker impedance and the low frequency range.
You can forfeit some low frequencies by choosing less capacitance.
You can choose higher impedance speakers, but the penalty is that less power will be delivered because of the low voltage available.
