Combined with the nacked design choice, it gives our products an again better self-healing capability as well as a very good capacitance per volume ratio. This also means that internal construction of the multilayer stack, usually hidden in encapsulated film capacitors design, is visible at the cut edges in the surface mount configuration. In a typical film capacitor stack, hundreds of film layers are compacted during manufacture. Under a micro- 6 scope these have the appearance of pages in a book. Subsequent manufacturing and pcb assembly processes allow a small amount of relaxation in these layers. In some cases, small gaps between layers may become visible. These are referred to as microgaps, and their occurrence is a standard feature of this technology. Even if it can be considered an cosmetic issue, presence of these gaps has no effect at all on mechanical or electrical performance or reliability. (Detailed report is available upon request.)

Once the sealed bag is opened, the capacitors must be stored in a dry atmosphere until soldering. Recommended storage conditions are: PET & PEN: < 30C and R.H.<60% for a maximum of 168 hours PPS: < 30C and R.H.<60% for a maximum of 4 weeks The use-by date is 3 years if kept in origin plastic bags. In case of storage outside the conditions recommended above the capacitors must be dried prior to soldering. Recommended drying conditions are: 48 hours minimum at 60C and RH < 10%. 9
