The polyester film is most reliable and together with PP most used of plastic films. It can be produced in thicknesses down to 0.7 μm (0.03 mils). Its tensional stability is high and it’s εr ≈ 3.2. This has facilitated the manufacture of one for organic dielectrics very space-saving capacitor. A typical field of application is decoupling. Certain applications like switched mode power supplies (SMPS) require for filtering and decoupling purposes large capacitance and moderate losses which have made the MKT capacitor an attractive replacement for the relatively expensive ceramic X7R capacitors.

It is common knowledge that leads time is often a critical aspect of Procurement of EEE parts for Space Applications. Some specific family types usually suffer from having long lead times (more than 1 year on some occasions), which makes them a major driver on any procurement. One of the most affected families are Space Qualified Panel C Mounted EMI filters.

Tantalum (Ta) capacitors and multilayer ceramic capacitors (MLCCs) are two widely accepted capacitor technologies that can be employed in a wide range of electronics applications. Although both technologies perform the same basic function, they are very different in terms of their construction techniques, materials, and performance under various conditions, so it’s important to understand the potential impact of selecting one over the other.
