Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Capacitor-Input filter (125V AC Supply) | 125 V | — | — | — | 100 mA |
| Capacitor-Input filter (220V AC Supply) | 220 V | — | — | — | 100 mA |
| Capacitor-Input filter (250V AC Supply) | 250 V | — | — | — |
Application Notes
When a filter-input capacitor larger than 40 uF is used, it may be necessary to use more plate-supply impedance to limit peak plate current.
