Application Notes
Designed for use in regulated power supplies or voltage amplifiers operating at plate potentials between 300 V and 4 kV. Particularly useful as a shunt or series regulator in equipment requiring stabilized output voltage. Also well suited for sweep circuits employing electrostatic deflection. Current limiting series impedance must be used if peak voltage exceeds maximum ratings.
