Fuse (electrical)
A fuse consists of a metal strip or wire fuse element, of small cross-section compared to the circuit conductors, mounted between a pair of electrical terminals, and (usually) enclosed by a non-combustible housing. The fuse is arranged in series to carry all the charge passing through the protected circuit. ...

A capacitor is not a fuse. Unlike a fuse it is undocumented how a capacitor fails. What I mean to say is: - when a fuse fails, it breaks the circuit and the circuit it safe. - when a capacitor fails, it may either break the circuit or short it. To prevent a capacitor from failing ...

Capacitor Basic Calculations
Capacitors are used in many circuits for different purposes, so we''re going to learn some basic capacitor calculations for DC circuits. In the paragraph: "If we needed to store a charge of say 0.0002 coulombs then we just divide this by the voltage, in this case 12V to see we need 0.0024 Farads or 2,400uF microfarads."

The fuse you have selected is a fast acting fuse but the thermal mass of the fuse will unlikely respond in the short time that it takes to charge a 10uF capacitor. You will always have a certain amount of series resistance in the wiring, connectors, PCB traces that also will help to limit inrush current.
