Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Pentode | 200 V | 4050 | 100000 | 42 | 7.1 mA |
Application Notes
Suitable for modulation, gating, and variable reactance applications, where only a small input is available. A diode has been tied to the suppressor grid to prevent blocking when this grid is under positive drive conditions.
