Description
The CL 12.00 is a series of type II ceramic disc capacitors with radial leads, rated 500 V DC, for general-purpose circuits [1]. The Agenda radioelectronistului (2nd edition, 1989) gives three groups by the change of capacitance with temperature – CLX, CLY and CLZ – with 13 rows and 33–10000 pF [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 the ceramic capacitor line of IPRS passed to IPEE Curtea de Argeș in 1973 [5].
Coded as [3]:
| Part | Meaning |
|---|---|
| CLX | construction type: undefined temperature coefficient, capacitance change −70…+30 % from −40 to +85 °C (relative to 20 °C) |
| CLY | the same, −90…+30 % |
| CLZ | the same, ±20 % |
| 12 | technological family („familia tehnologică”) |
| 06…19 | package code („codul capsulei”) |
Marked in clear, the code is followed by the nominal capacitance and the tolerance; the book’s example is „CGA 12.06 — 4,7 ± 0,5” (4.7 pF, tolerance 0.5 pF or %) [3].
In colour code, fig. 20.50 (type I ceramic) shows five marks, a to e, and fig. 20.51 (type II) three marks, a, b and c, the last labelled „Dielectric sau toleranța” (dielectric or tolerance); the book’s colour table [3]:
| Colour | a: temperature coefficient (10⁻⁶/°C) | b, c: digits | d: multiplier | e: tolerance, C > 10 pF | e: tolerance, C ≤ 10 pF |
|---|---|---|---|---|---|
| black | 0 | 0 | 1 | ±20 % | – |
| brown | −33 | 1 | 10 | ±1 % | – |
| red | −75 | 2 | 10² | ±2 % | ±0.25 pF |
| orange | −150 | 3 | 10³ | ±3 % | – |
| yellow | −220 | 4 | 10⁴ | – | – |
| green | −330 | 5 | – | ±5 % | ±0.5 pF |
| blue | −470 | 6 | – | – | – |
| violet | −750 | 7 | – | – | – |
| grey | – | 8 | 10⁻² | – | – |
| white | – | 9 | 10⁻¹ | ±10 % | ±1 pF |
| gold | +100 | – | – | – | – |
The table also has a tolerance „/+50” for CLX and CLY, which the list of characteristics (±10 %, ±20 %, −20…+80 %) does not have [1]. The 1st edition gives other ranges in most rows, the series E3 for CLX and CLY (2nd edition: E3/E6), the lead spacing as 5 and 7.5 mm (2nd edition: 5.1 and 7.6), and refers the temperature change to „−20 °C” (2nd edition: +20 °C) [2][1]. The standard is printed „STAS 9507/74” [1].
Rated voltages are DC („Vcc”). Dimensions in mm (fig. 20.54): maximum diameter Dmax and lead spacing d from the table; thickness max. 4; leads Ø 0.6, at least 30 mm long [1].
