Q:

Help identifying capacitor-like symbol with a bracket or "U" shape on one side

I came across a circuit diagram online which I want to modify for a circuit I am designing but I wasn't sure about one of the components in the diagram.
The component is labeled as CP has a value of Farads so I'm assuming it's just a capacitor but after searching around I couldn't confirm if it was or not
Is it some kind of special component or just an odd circuit symbol for a regular capacitor?

A:

That is a symbol for an electrolytic capacitor. The cup shape is meant to imply the type of capacitors that are often manufactured in an aluminum can.
