Its form factor makes it well suited to both PCB and Chassis mounting.

Working Principle

The SPSX151M04R-7 capacitor works on an electrolytic principle, relying on a chemical reaction between two metals. This reaction creates an electric field that is used to store charge and discharge energy to the capacitor. When electrons enter the capacitor, an accumulation of electric charge builds up between the two metal plates. This charge forms a potential difference, which in turn creates an electric field between the plates.

The electric field generated between the two plates is then used to store energy. When a current is applied to the capacitor, the electric field created pushes the electrons into the drain, and the electric charge stored in the capacitor is discharged. The same principle applies when the capacitor is being recharged.

When a load is connected to the capacitor, its internal structure changes and a shift in the electric field is created. The electric field affects the polarization of the molecules, which in turn affects the electric charge stored in the capacitor. As the electric field is influenced and changed by the load connected to the capacitor, the electric charge stored in the capacitor also changes and this is what allows the capacitor to deliver electrical energy.
