Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Triode section typical characteristics | 100 V | 2500 | — | 70 | 3.5 mA |
| Pentode section Class A | 170 V | 7500 | 16000 | 9.5 | 41 mA |
| Pentode section Class A maximum output | 200 V | 6400 | 20000 | 9.5 |
Application Notes
The triode section can be used without special precautions against microphonic effect in circuits in which an input voltage Vi >= 10 mVeff gives an output of 50 mW.
