Which Capacitor is which!!! please help!

[DanAngus]

Hey Guys,

I have a question.

Im brand new to this stuff, and i need a .15mf electrolytic(or similar) capacitor.

I got 2 capacitors, i have been told that one of them will work

One is a .15mf Panasonic capacitor

and the other is a 15mf electrolytic capacitor(i think)

lol

but Aron said that the .15 mf panasonic would work.

but theres one problem.. i just got my box of supplies from small bear in today. but i guess they would think that i know the difference between the 2 capacitors. But i have no idea!

so hears some pictures, and would you guys be able to tell me which one is the .15mf Panasonic capacitor?

Thanks alot(sorry about the blurryness/ picture size)

Showing us a Fuzzy picture of a Cap isn"t going to help us help you very much...Capacitor Values are determined by the Code written on the Capacitor, Every small Value Capacitor will have a 3 number code written on them followed by a letter or two....

Here is a Code calcultor that will tell you the Value of the Cap based on the code written on the Cap....

The orange cap is a tantalum cap,

the other cap is a film cap, that'll be your panasonic one

The one on top in the first photo...

The larger,square one on the bottom in that photo.

Make sure you connect the tantalum capacitor the correct way around because I heard those things can go off like fire crackers!

If you already knew that, sorry, I didn't mean to be patronising. Just figured worth pointing out considering you were asking about which cap is which. It's not good when it all ends in tears and a mess.

Welll im sorry, see i didnt know that the numbers had any significance.

Yes, i didnt know that, but im going to use the panasonic Cap. thanks for the reply!

The numbers are significant, but there are a few different methods of labeling those suckers!!    2 digits, especially if underlined, usually mean pF (ie, 10 = 10 pf, typically a pretty small cap physically, too!).
 
The 3 digit codes are read like a resistor in a way, and the scale "starts" in the pF range; the first 2 are your figures, and the last is a multiplier.  So, a cap reading "221" would be 220 pf. 
"472" would be 4.7 nf...."123" would be 12nF.  This is due to an implied 10 to the power of {insert multiplier here} *  the first 2 numbers.   Like, 47*10^2 = 4700pF, = 4.7nF after you move the decimal 3 places left to convert to nF.   
Pretty crappy, isn't it? Using that cap calculator helps a lot!   The "plastic" ones, such as yours there, typically have their value right on them, like ".15" for 150nF, which is the same as .15uF.   You'll get the hang of it!
;o)

This link won't tell you the value but it will help you identify your part.
