Description
The P cermet trimmer potentiometers are cermet presets for horizontal or vertical mounting, made to STAS 9614/2-74 for professional electronic circuits: four types, P-35571 and P-35572 for horizontal and P-35573 and P-35581 for vertical mounting, from 10 Ω to 1 MΩ, rated 0.5 or 1 W at 40 °C [1].
The Agenda radioelectronistului names IPEE Electro-Argeș of Curtea de Argeș and IIS Electronica of Bucharest as the producers of the potentiometers in its section on potentiometers made in Romania, in both editions, without saying which works made which type; they are listed here under Electronica [3][4]. Electronica românească. O istorie trăită, vol. I, says that Electronica imported in 1969 a production line for film potentiometers from Siemens (West Germany), and that it made single potentiometers with or without a mains switch, tandem and push-button potentiometers, defined by its internal norm NID 2195-67 [5].
The book does not explain the codes [1]. The 1st edition (1983) gives the same data [2].
Rated power at 40 °C. Dimensions in mm: see the drawings (fig. 17.4 a…d) [1].
