I searched, everywhere, including this forum. I canít seem to find them anywhere.
Most are 11mm tall. What is considered ďlow profileĒ???
My head is going to explode.
Does anyone have a source? 
A way to search? Low profile gives no returns.

I've noticed more caps marked as low impedance. Are those the same as low esr?

I tried to read up about ESR and there is a math equation that includes a bunch of stuff. Resistance is part of it. There is TAN with a squiggly icon after it which is an indicator. I guess it matters what the circuit is around itÖ I donít know.

The low-profile caps I have are just under 6mm (can't make out the brand mark), but these Panasonic's are listed as 5mm length. Length is what you want to search, and it seems that around 5mm height is what you need to be "low profile"

IDK if this link will work, but here's the search I did:
https://www.mouser.com/c/passive-components/capacitors/aluminum-electrolytic-capacitors/aluminum-electrolytic-capacitors-radial-leaded/?diameter=4%20mm~~6.3%20mm&length=5%20mm&voltage%20rating%20dc=16%20VDC~~450%20VDC&instock=y&rp=passive-components%2Fcapacitors%2Faluminum-electrolytic-capacitors%2Faluminum-electrolytic-capacitors-radial-leaded%7C~Voltage%20Rating%20DC%7C~Diameter

That is a great link thanks Jessenator! Iím gonna save that and stock up.

Another crazy long link. Anything between 5 and 7mm length is what you want. But, also be careful of the larger values. 100uF low profile gets pretty chunky.

Low ESR is a different matter. However, I do have a link for a low profile low ESR cap I've used often!!
