Key Features
  • 1/4-Watt Filament Type
  • Low plate-filament capacitance
  • Suitable for r-f source
  • Filament observation aperture

Application Notes

The design of the filament permits operation within 10% of rated voltage. Due to low wattage and low capacitance, it is specifically suited for high-voltage rectified power from r-f sources. Filament temperature observation is required when using r-f sources.
