The issuing of the second volume, following the first volume “Electronic components and materials textbook” PAPASOTIRIOU Publications Athens 1997)1, arises by the need of the first and second2 levels of education in Greece and the market of a tutorial concerning the technology of electronic components. Hopefully, there will be a third volume too. I strongly believe that, for the people occupying themselves with electronics, some topics are not adequately known:

  • special ferrites
  • dimorphic and uniform elements
  • ways of cutting piezoelectric crystals
  • magnetic amplifiers
  • presentation of over 60 sensors etc
I would also like to mention that at the end of every chapter a part of the bibliography used is presented. And I say part, because not every reference is provided.
In the era of rapid social and technological processes, we should be as more socialized as possible and through the cooperation with other people or organizations, we should all try to achieve our goals. Thus, ensuing this cooperation attitude, I present you my project and would like to express my acknowledgements to everyone who cooperated for an even better result.
More specifically, I would like to thank for the excellent cooperation the following people:
  1. Dimitrios Frantzeskakis, professor in the University of Athens, for his observations.
  2. Kostas Dimopoulos (Sales Manager) and Kostas Kissas (Manager of the Department of Crystals) of Netcom S.A. for the informative material they offered me.
  3. Konstantinos Priftis, candidate Ph.D. philologist of the University of Athens, for the linguistic editing of the second volume.
  4. Athanasios Stamoulis, publisher, for the trust he showed.

  1. ELECTRONIC COMPONENTS AND MATERIALS TEXTBOOK Volume I is devoted to materials which are used (conductors, insulators, semi-conductors), resistors, capacitors, coils, RC-LC networks, EMI/RFI and SAW filters as well as the resonators.
  2. A part of A’ and B’ Textbook Volumes have been already included in the matter of courses “Technology of Provisions Electronic” and “Technology of Provisions of Electronics and Study of Drawing” (OEDB Publications, 2000) respectively in the A' and B' circle of TEE.
Seven years after the publication of the first volume, the second volume of the author Thanassis Giokas is now issued, which completes the project referring to passive components (this term is relevant as for instance the sensors are passive or active based on the circumstances). The importance of passive elements is great in electronic as their turnover exceeds 90% of the equivalent amount of active components.
This volume consists of five chapters (6th to 10th) and an appendix which contains representative topics for passive components available in the market.
The sixth chapter is devoted in ferrites and their attributes and more specifically, in the forms, the materials, the adjusters, the self-inductance and the special ferrites.
The seventh chapter shows the piezoelectric ceramics and their attributes, elements and applications in dimorphic and uniform elements. The eighth chapter examines the piezoelectric crystals, setting out the ways of cutting, the equivalent circuit, the parameters, the attributes and the operation and using codes.
The ninth chapter covers the transformers; the equivalent circuits of single-phase transformers, the auto-transformer, the line transformers, the composite resistor transformers, the voltage transformers and the auto- transformers pf special and general implementation which are met mainly in electronics.
At the end, in the tenth chapter which looks through sensors, transducers and actuators, a great amount (over 60) of those components is checked, providing many operational elements of their structure and use. The presentation of such an extended number of components covers a void the Greek bibliography had.
This volume, as well as the previous one, is addressed to students and to professionals or amateurs of electronics. For each, this project can evolve in a very useful textbook, which can be the source of valuable information, according to every need.
