Title: Tantalum Polarity
Post by: rdagger on April 04, 2006, 01:41:22 am

How do you tell the polarity of a tantalum capacitor? I though it was by either a plus or a vertical line. I have ones with both -- see the drawing.

btw: the leads are the same length and my drawing is accurate.

Personally, I'd be inclined to trust the "+" sign.

Additionally, this (http://www.ionpool.net/arcade/tech/bw_vector_monitor_faq.pdf) seems to indicate that the "thick bar" is the probably the "-"side as well:

"Check the polarity on the existing capacitor (there is a thick bar on the capacitor, 75% of the time, it's the - side). The + side of a capacitor has a longer lead if the outside markings are confusing"

That being said, I don't really know for sure.
