Application Notes

One method of mounting the 8083 is to use a stainless-steel 'T' bolt to attach the mounting base of the tube to a chassis or circuit board. Torque used to tighten the nut should not exceed 3 inch-pounds. Grid-circuit resistance may be calculated using (10000 + 100 RK + 10 RL) ohms.
