Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Sharp cutoff R.F. pentode | 250 V | 4600 | 1300000 | 48 | 7.4 mA |
Application Notes
Circuit operation with cathode bias is recommended. At heater voltage = 5.0 volts the typical value of transconductance will decrease to about 4000 micromhos.
