Description
The RBA 3000 and RBA 3000-L are wire-wound resistors in a square ceramic body with axial leads, made to STAS 9288-77, RBA 3000 for general use and RBA 3000-L for professional circuits [1]. The Agenda radioelectronistului (2nd edition, 1989) lists eight sizes, RBA 3002 to RBA 3020, each printed for both series („RBA 3002(-L)”), from 2 to 20 W and from 0.1 Ω to 68 kΩ [1].
The Agenda radioelectronistului names IPEE Electro-Argeș of Curtea de Argeș as the producer of all the resistors in its section on resistors made in Romania, in both editions [3][4]. Un secol de electronică în România says that the works, founded in 1972 as ICEP, took over the resistor lines that IPRS Băneasa made under a Thomson-CSF licence: the carbon resistors in 1973 and the wire-wound resistors in 1974 [5].
Coded as [3]:
| Part | Meaning |
|---|---|
| RBA | construction type: wire-wound resistor in a ceramic body („rezistor bobinat în corp ceramic”) |
| 3 | package type („tipul capsulei”, 1…6) |
| 002…020 | rated power: 2…20 W |
| -L | constructive variant: high reliability („cu fiabilitate ridicată”) |
Romanian resistors are generally marked in clear, with the series code, the nominal value (100 = 100 Ω, 1 K = 1 kΩ, 1 M = 1 MΩ), the tolerance and the rated power [3].
The 1st edition (1983) calls the series RBA and RBA-L and has the same table; the codes RBA 3016 and RBA 3020, damaged in the 2nd edition, are read from it [2][1].
Dimensions in mm (fig. 16.9, 16.10): maximum length Lmax and side a (± 0.2) from the table; leads Ø 0.8 ± 0.01, at least 30 long [1].
