I have a 1000μf 6.3v capacitor that needs replaced. 1) Can I replace it with a capacitor that has a higher μf rating? 2) I have a 1500?? 6.3v capacitor, or what I believe is a capacitor, but I don't know if the 1500 is μf, nf, or pf. 3) I'm attaching a picture of what I believe is the capacitor I would use to replace the other one. And of the one needing replaced. Really all I need to know is what the unit is on the silver capacitor in the picture and if I can use that to replace the black one.
