CV521 cold cathode discharge tube
 |
This valve measures 240x30mm overall |
| Max anode voltage | 1800V |
| Max mean anode current | 100mA |
| Max value of discharge capacitance | 10µF |
| Max frequency of discharge | 4pps |
| Trigger voltage | 20 to 30kV |
| Ambient temperature range | -37 to +140°F |
The trigger voltage is provided by, for example a car ignition transformer, the secondary of which is connected to a few turns of bare wire or a metal band around a length not exceeding one inch of the midportion of the tube.
The anode is indicated by a red marker ring
