Description
The CTS-M 20.00 is a series of solid-electrolyte tantalum capacitors in a metal case with a glass feed-through and axial leads, for general use at low frequency in professional circuits, made to CEI 361, 361 C, 325 and NID 3412-79 [1]. The Agenda radioelectronistului (2nd edition, 1989) lists 76 codes, CTS-M 20.01 to CTS-M 20.76, with 1–330 µF at 6.3–63 V, each in one of five case sizes [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.
Coded as [3]:
| Part | Meaning |
|---|---|
| CTS | solid-electrolyte tantalum capacitor („condensator cu tantal, cu electrolit solid”) |
| M | construction variant: metal–glass feed-through case („capsulă de trecere metal-sticlă”) |
| 20 | technological family („familia tehnologică”) |
| 01…76 | package code („codul capsulei”) |
The capacitors are marked in clear; the book’s example „CTS—M 20.05—33/6,3” gives the code, the nominal capacitance (33 µF) and the rated voltage (6.3 V) [3].
The table of case sizes also gives, in mm, the dimension l, the number of modules the capacitor takes on the board and the diameter and type of the insulator [1]:
| Case size | l | Modules on the board | Insulator diameter | Insulator type |
|---|---|---|---|---|
| 1 | 4.32 | 7 | 2.5 | 1 |
| 2 | 4.12 | 8 | 4.3 | 3 |
| 3 | 5.3 | 10 | 5.3 | 4 |
| 4 | 5.2 | 10 | 7.2 | 5 |
| 5 | 5 | 13 | 7.2 | 5 |
Printed so in both editions: 20 µF (CTS-M 20.56) and 37 µF (CTS-M 20.58) [1][2]. The capacitance of CTS-M 20.29, 15 µF, is read from the 1st edition [2]; in the 1st edition the code CTS-M 20.42 has a broken digit and reads „20.12” [2].
Rated voltages are DC („Vcc”). Dimensions in mm (fig. 20.47): diameter D, length L, lead diameter d and the hole spacing L′ on the board from the table of case sizes; leads 35 ± 5 mm long [1].
