I thought it would be nice to have a picture of the Teflon cap lineup for those thinking about trying them as bypass or coupling caps.

On the left is a well worn ruler. You can see the FT-3 0.47uf 200V cap is just under 3 inches long. Then comes the 0.22uf 600V and the 0.10uf 600V caps. The tiny one on the left is the FT-1 0.01uf 200V cap. This is a more workable size for a Dac or other applications where space is a big issue.
The quarter in the upper right corner didn't image very well, but gives you as second point of reference.
