Capacitors are fundamental components in both analog and digital electronic circuits. These passive components play an important role in influencing the operational behavior of circuits. The characteristics of a capacitor vary mainly depending on the dielectric material used. The dielectric material determines the capacitance value, energy efficiency, and size of a capacitor. Fixed value capacitors can be broadly categorized into two: polar and non-polar capacitors. Non-polar capacitors include ceramic, film, and paper capacitors.

The goal of passive components’ failure analysis (FA) is to determine the root cause for an electrical failure. The findings can be used by the manufacturers to improve upon the design, materials, and processes used to create their components. This leads to better quality and higher reliability components. The FA also provides feedback for the users to improve their handling, storage, and applications of these components.

The double-stage filter family is therefore also appropriate for applications with particularly high EMC emissions, as is frequently encountered in industry. Typical applications include machines and systems for automatic production, motor drives and industrial plant machinery. These powerful filters are also the first choice for modern frequency inverters for motor control.

The capacitors are rated for voltages from 500 V DC to 1600 V DC, offer capacitance values from 0.47 µF to 170 µF and are suitable for a maximum operating temperature of up to 105 °C. At a rated voltage and operating temperature of 70 °C, the typical life of the rugged, self-healing and RoHS-compliant capacitors is 95,000 hours.

X-class capacitors are used across the line where failure would not lead to an electrical shock. X-class capacitors are divided into sub-classes and Y-class capacitors are used in “line-to-ground” applications where failure could lead to an electrical shock. It is also divided into sub-classes by their AC voltage and peak surge voltage ratings.
