The compendium 'ABC of Capacitors - Fundamentals, Properties, and Types of Capacitors' comprises nearly 80 pages and is available in both German and English. The author, Stephan Menzel, provides an introduction to capacitor technology and describes the variety of capacitor types along with their properties and parameters. The book can be used as an introduction for students or as a refresher to solidify knowledge about capacitors and their applications in assemblies. The 'ABC of Capacitors' serves as a reference work that succinctly presents the relationships and technical characteristics of capacitor technology. It begins with an introduction to the relationships between electric fields and permittivity, as well as the structure and operating principle of a capacitor. The electrical parameters and properties, along with their interrelations, are outlined so that users know what to consider when selecting capacitors. This is followed by a detailed overview of the available types of capacitors and a bibliography.
