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.

Today, one can hardly find a consumer, industrial or high-reliability electronic device that does not make use of a voltage regulator. Designers basically use two types of regulators, linear LDO (low dropout) and step-down switch-mode DC/DC regulators to convert the voltage to lower level. Switching DC/DC regulators are preferred for applications that require a greater difference between input and output voltages because they are more efficient in such operating conditions.

Lasers nowadays are one fabrication tool among many for industrial production, measuring and testing applications. Industrial lasers commonly employ a pulse grade capacitor to generate and deliver the energy required to test, measure or make the product or service on offer. In this article, we examine the importance of the self-healing characteristics of metallized film dielectrics used in pulse grade capacitors for industrial laser applications.
