Resolution: Group | Duration: Two to four hours



The goal is to calculate the quantitative reliability indicators of an electronic system – failure intensity of components and the system at large, probability of failure-free operation, failure probability and the average time of failure-free operation of the whole electronic system.

Learning Objectives

At the end, the students will be able to: • calculate the failure intensity of electronic components by using ItemTool Kit application; • determine the probability of failure-free operation of the electronic system; • define the components that most influence the reliability of the electronic system.


Reliability is a quality of the components and objects to keep their technical indicators for a specified period of time under given running conditions in particular electrical and thermal modes. To calculate it, it is necessary to thoroughly know the electronic system (in this case, a DC/DC converter), to select a calculation method (MIL-HDBK-217F, FIDES, RDF2000, 217PLUS, etc.), and to define the electrical and thermal modes of the components involved in the system
