Zuki,

What is your idea of thin? We've used some two-color ones that are about .030 x .060 rectangle, and probably less than .020 thick. Dimensions in inches. These are surface mount devices, meaning they mount on the "surface" of the P.C. board, they do not have leads that go through the board. If you give a hint at your application, it would help provide advice.

I'd like to have something about 2mm thick circular or rectangular with an optical coating would be fine.. I'd like them to be able to connect from the sides so I can make an array.

the lowest voltage keeping the highest luminence possible... they also have to be able to withstand freezing tempuratures.. ?

thanks!

Check out this part, it's made by Avago, the company that got spun off of HP's LED and RF component line.

It's a three color LED that's only 1.1mm tall.

They also have an application note that goes into detail about how to drive an LED matrix, here's the link.

What are your requirements? What are your not to exceed dimensions?
