Note:
1. At frequencies above 50 MHz, the filament voltage of ITK12-1 is reduced so that the ratio of filament voltage to current becomes the same as that without an anode voltage.
2. Measured with a 40 x 40 cm shielding plate attached to the grid plate.
3. Limited conditions above 30 MHz. Please consult Pilani Electron Tubes & Devices.
4. Operation with higher frequencies on request.
