Hello,

Is a tantalum capacitor polarized? If so how do I know what is the cathode and what is the anode?

Thanks!

One other thing to mention, they are not fireproof. Get it wrong and they can light up like a match head. Good parts other than that.

But yet I can find no good reason of why all the manufacturers are doing so instead of marking the negative terminal like other polarised capacitors.

:D
This has always been a mystery to me too. It reminds me of all those crazy UK people driving on the wrong side of the road. ;)

Just kidding guys. I couldn't resist. Bill will you defend me when the lynch mob comes to get me? :eek:

I can tell you this about metal can tantalums. If you apply the polarity one direction, it's a capacitor. If you apply the polarity the other direction it's a blasting cap! (I've been "shot" by blasting caps...er...tantalum capacitors on numerous occasions. :D

And the two terminals of a polarized capacitor are not named anode and cathode, just the positive and negative terminals.
