Description

The PMM205 is a metallised polypropylene capacitor for alternating current, in a cylindrical can 35 mm in diameter with three tinned lugs for mounting on a printed circuit, used in the filament circuits of electron tubes [1]. The Agenda radioelectronistului (2nd edition, 1989) gives a single value, 5.3 µF ± 10 % at 250 V AC; the 1st edition (1983) has the same data [1][2].

The Agenda does not say which works made the series: for the whole section on capacitors made in Romania it lists IPEE Electroargeș of Curtea de Argeș, Tehnoton of Iași, IIS Electronica of Bucharest and IPRS Băneasa as producers, and the 1st edition (1983) names only the first three [3][4]. It is listed here as made by IPRS Băneasa.

In the book’s list of letter codes PMM stands for metallised polypropylene capacitors; the heading of the series spells the dielectric „propilena”, and the code PMM205 does not have the two pairs of digits of the other codes [3][1]. Lugs 1 and 2 are the poles of the capacitor and lug 3 only fixes it [1].

Dimensions in mm (fig. 20.33): Ø 35, height 53, lugs 10 long; in the base view lugs 2 and 3 are 10.1 apart and 14.4 below lug 1 (printed „101” and „144” in the 2nd edition) [1][2].
