Description

The EG 70.00, EG 72.00 and EG 73.00 are series of high-capacitance aluminium electrolytic capacitors, given in one table of the Agenda radioelectronistului (2nd edition, 1989), made to STAS 7675-73 for filtering in low-voltage rectifiers; the negative terminal is marked with paint [1]. The table lists nine codes, EG 70.20 to EG 73.50, with 680–6850 µF at 25–63 V, the maximum ripple current I0 of each value and one of six drawings, a to f [1].

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; Un secol de electronică în România says that IPRS made seven types of electrolytic capacitors, from 1 µF to 10,000 µF and from 3 V to 450 V [5].

Coded as [3]:

Part	Meaning
EG	construction type: electrolytic capacitor (of high capacitance)
70, 72, 73	technological family („familia tehnologică”)
20, 21, 25, 26, 27 (EG 70); 40, 70 (EG 72); 35, 50 (EG 73)	package code („codul capsulei”)

The capacitors are marked in clear; the book’s example „EG 52.43—22/16” gives the code, the nominal capacitance (22 µF) and the rated voltage (16 V) [3].

Values kept as printed in both editions: EG 72.40 has 1000 µF at 25 V twice, with 600 mA and 70 mA, and EG 72.70 has 4750 µF and 6850 µF [1][2]. EG 70.20 and EG 70.21, and EG 70.25 and EG 70.26, share one cell and differ only in the drawing (a or b) [1]. For EG 73.50 the 1st edition prints the third ripple current as „000” (2nd edition: 900) [2][1].

Rated voltages are DC („Vcc”). Dimensions in mm (fig. 20.39 a…f): diameter D and length L from the table; a, b – axial, with insulation; c – M16 threaded stud and one lug on one end; d, e – two lugs on one end, with insulation; f – base with three pins [1].
