Reliability and lifetime model of passive components

The reliability of passive electrical components such as capacitors and circuit boards is a key characteristic for the success of the energy transition, e.g. in the areas of power grid expansion, e-mobility or Industry 4.0. However, a verified lifetime model of these basic electrical components is still lacking. The aim of this project is therefore to investigate the quantitative influences of electrical, thermal and mechanical loads on passive components. To this end, passive components from different manufacturers are compared, stressed under laboratory conditions and the results statistically evaluated. Electrical parameters such as the remaining capacity, the impedance or the partial discharge inception voltage are used as performance indicators. The development of these indicators over time and as a function of different levels of the considered stresses is mapped in a statistically validated lifetime model.
