| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Anodenruhestrom | 200 V | — | — | — | 9 mA |
| Characteristics | 90 V | 1500 | — | — | 5 mA |
| Electron-coupled circuit | 160 V | — | — | — | 2.1 mA |
Application Notes
Maximum ratings are for a limited life of approx 50 hours. For normal life, cathode current should not exceed 6 mA. The tube is intended to be soldered directly into the circuit.
