Description
The EG 74.00 is a series of polarised high-capacitance aluminium electrolytic capacitors in a cylindrical case with axial leads, made to STAS 7675-73 for filtering in low-voltage rectifiers [1]. The Agenda radioelectronistului (2nd edition, 1989) lists seven package codes, EG 74.73 to EG 74.80, with 100–6800 µF at 16–100 V and the maximum ripple current I0 of each value [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) |
| 74 | technological family („familia tehnologică”) |
| 73…80 | 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].
Both editions print the leakage-current coefficient as 0.3 (the other EG series have 0.03 or more) [1][2]. Several cells of EG 74.73 are smudged in the 2nd edition and are read with the 1st, which has the same values [1][2]. The drawing gives one lead as „max60±2” [1].
Rated voltages are DC („Vcc”). Dimensions in mm (fig. 20.37): D ± 0.8 and L ± 1 from the table; leads Ø 1, one at least 38 mm long [1].
