The content of precious metals in electronic components differed depending on their purpose and type. As a rule, a relatively large amount of used platinum, palladium, gold and silver. And as a rule, these elements are only in older (especially Soviet) electronic components. In the modern precious metals usually do not exist.
Below is a detailed list of electronic components with specific names, which are relatively rich in precious materials.
Typically, these metals are contained in the details of a relatively simple design - condensers, resistors, switches, connectors.

The gold is contained in large amounts in sophisticated electronic components. Mostly, of course, in the details of the Soviet period, however, imported components, gold is also present, but in relatively small quantities. Some national radio Golden elements located sometimes openly, but often they are hidden under a copper case (because gold is very easily abraded).

Silver contains the vast majority of electronic components in the form of ultrathin (several tens of microns) layer on the outside or inside of the case and on the contacts of electronic components. Therefore, to separate the individual electronic components do not make sense. In a very larger amount of pure silver contained, except that the relay contacts.
Therefore, as an example, is considered the approximate content of silver in electronic components for various purposes in the amount of 1,000 individual e-component.
Capacitors:
K15-5 – about 29,901 grams.
K10-7V – approximately 13,652 grams.

РКМП1 – about 132 grams.
RVM – about 897,4 grams.
Note that the following list of precious metals in electronic components is not complete (unfortunately, the preparation of such it would take several dozen pages). Therefore, the article considers only the "rich" electronic components. However, the interested reader may complement this list yourself by reviewing passports for radio and radio equipment, and by acquaintance with the special literature on radio.
