| Description |
Subminiature gas tube used as time totalizer. Metal is sputtered off the cathode and deposits on the collector when current flows. With a constant current of 0.36 mA DC the collector resistance drops from 40 to 6 ohms after 1000 hours.
This JEDEC code corresponds either to Bendix TD-60 and to TD-70, the major difference being the body lenght.
