Failures are classified into catastrophic failures, where functionality is completely lost, and degradation failures, which are defined as failures where characteristics deteriorate and fall outside acceptable ranges. The failure mechanism is the "process leading to failure." In other words, it is the process by which various causes such as electrical, physical, mechanical, and chemical lead to failure. This document also covers the differences between failure modes and failure mechanisms, as well as the basics of capacitors, how to choose and use them. We encourage you to read it.

There are several failure modes for capacitors, and the frequency of occurrence varies depending on the type of capacitor. Catastrophic failure of a capacitor can result in an open or short circuit. This failure can lead to the explosion of the casing, smoke, fire, damage to other electrical components, and leakage of liquids or gases from inside the capacitor. This document includes information on capacitor failure modes and mechanisms, as well as lifespan estimation, selection, and usage. We encourage you to read it.

Al-Ecap offers a large capacitance per unit volume and excellent cost performance due to its unique electrodes made from a porous material with a large surface area and a thin dielectric with a high relative permittivity. However, AL-Ecap tends to have a shorter lifespan compared to MF-cap under operating conditions that involve high electrical and thermal stress, leading to faster degradation and failure. This document includes not only the causes of failure for representative capacitors but also the basics of capacitors and lifespan estimation. We encourage you to read it. 【Contents】 ■ Introduction ■ Basics of Capacitors ■ Failure Modes and Mechanisms ■ Lifespan Estimation ■ Selection and Usage ■ Conclusion *For more details, please download the PDF or feel free to contact us.

The function of a capacitor is to "not allow direct current to pass," "instantaneously store and release charge," and "allow alternating current to pass." When these functions are lost, it results in failure. The failure rate is defined as "the ratio of a system or component that, after operating without failure for a certain period, experiences a failure within the subsequent unit period." In other words, the failure rate is "the rate at which failures occur" and is a quantitative measure of reliability. This document covers the basics of life estimation, failure modes and mechanisms, selection and usage, among other topics. We encourage you to read it.

Failures of capacitors can be attributed to environmental factors such as temperature, atmospheric pressure, and vibration, as well as electrical factors like operating voltage, ripple current, and charge/discharge duty cycle. As the temperature rises, the chemical reactions within the capacitor accelerate, leading to a shorter lifespan. It is important to consider not only the ambient temperature but also various factors such as heat generation from ripple current and radiant heat from other heat-generating components. This document covers not only how to select and use capacitors but also includes information on lifespan estimation, failure modes, and failure mechanisms. We encourage you to read it.
