DESCRIPTION

The h32B is a three-electrode inert-gas-filled cold cathode tube designed for
use as a voltage reference tube. The third electrode is a starting element
for use in circuits having insufficient voltage available for breakdown at

the voltage reference point or requiring negligible overshoot of the reference
voltage when starting. This tube is free of parasitic oscillations and has an
exceptionally stable anode voltage drop characteristic.

Sufficient resistance must be used in series with the tube to assure

that electrode currents do not exceed their maximum rated values.

Note 2: The tube is capable of operating

at current values below the ratEd

"Minimum" value of h milliamperes in regulator applications where
lower current is required, however, operation at values below b
milliamperes for extended periods of time (hundreds of hours) may
result in an increase in regulation.

Note

(a)

between starting operations

The minimum starter current requirement applies
when tube is operated for extended periods (hundreds of hours)

to assure maintaining starter break-

down and transfer characteristics.

('0)

These values are for new tubes.

be considered during tube life.

Note

Note The anode voltage drop variation

Anode voltage drop will stabilize
The stability characteristic should

during a short period of tine (one

to ten minutes), with the tube operating at one value of current and
temperature within its ratings, will not exceed the above stated max-

imum value.

Note

The drift of anode voltage drop over a period of 1000 hours, with the

tube operating at one value of current and temperature within its

ratings, will not exceed the above stated maximum value.
After 1000-2000 hours operation the

improves with operating life.

Stability

drift of anode voltage drop per 1000 hours will not exceed 0.3 volt.
