Instead of using uniform deposition over the entire area of the film, the film is divided into a pattern of multiple tile shaped areas which are connected by thin fuse sections. When an insulation breakdown situation exceeding the self-healing capacity occurs, the fuse section melts to avert the insulation breakdown.

Protection of capacitor banks by fuses during energization and ...
The stress applied to the fuse assembly rated at 125 A is: 0.8 × 10-3 × (16900) 2 = 228 × 103 A 2 s. and even 200 A is unsuitable! This type of bank cannot be protected in this way using for example Fusarc-CF fuses. In some impossible cases, there is a solution that consists of protecting all three banks with a single common fuse (see …
Film capacitors: The versatility and stability you need for your ...
the round capacitor is not hard pressed; instead it is left round (Figure 11). Then, depending on whether the Al can is oil-filled or dry-filled, the capacitor goes through a process to place the bound capacitor inside the Al shell and fill with oil or resin. The capacitor, whether resin-filled or dry-filled, must be cured before it is capped off.
Film capacitor characteristics | Film Capacitor Fundamentals
Film capacitors use metalized film as the dielectric, and one characteristic of these capacitors is that they will cause an open failure if an overcurrent passes through them. This characteristic of film capacitors is referred to …
