Capacitors are cheap and any hobby electronics shop will sell you one.
Some are polarized Plus and minus
All have a voltage rating - same or higher voltage but never lower.
They're measured (rated) in micro-farads - symbol uF
Take the capacitor to the shop - or take the PCB to the shop - show the assistant what you want - pay pennies for the new component - un-solder the old and refit the new.
Amazon sell capacitors - but a local store would be better
