What kind of capacitor is that? Answered
So I've been trying to make a simple radio circuit based off of this schematic (http://www.electroschematics.com/wp-content/uploads/2010/02/small-fm-radio.jpg) , but I don't know the type of capacitor that's labeled "C4, 220uF/ 25V" and looks like ---l]---
I tried searching for the types of capacitors on Google, but I cant get anything more specific than "polarized". Could anyone please drop some knowledge on what that is?
