Inside, the lead wires go to two aluminum flashing disks that are the capacitor plates spaced 2.5cm (1 inch) apart. But in between them the dielectric consists of seven more aluminum flashing ...

That’s intuitive since getting the plates closer makes for higher capacitance but also makes the dielectric more likely to break down as the electric field inside the capacitor becomes higher ...

Selecting power capacitors requires an analysis of dielectric materials. Aluminum electrolytic capacitors are polar devices that feature a high volumetric density but cannot withstand reverse voltages ...

dielectric constant and loss tangent values tailored for specific device or circuit applications. In capacitor applications, ceramics with a high dielectric constant are used to increase the charge ...
