NOTES:
1) This is the maximum momentary current that can be handled if its full width
at half maximum is less than 10
碌s.
2) If the tube is operated near this or higher, the service life is noticeably reduced.
Use the tube within the recommended current values.
3) Measured under room illuminations (approximately 500 lux) and recommended
operating conditions. Note that these values may increase if the following
environmental factors are present.
1. Mercury lamps, sterilization lamps, or halogen lamps are located nearby.
2. Direct or reflected sunlight is incident on the tube.
3. Electrical sparks such as welding sparks are present.
4. Radiation sources are present.
5. High electric field (including static field) generates across the tube.
4) These are representative values for a wavelength of 200 nm and a light input
of 10 pW/cm
2
. In actual use, the sensitivity will vary with the wavelength of the
ultraviolet radiation and the drive circuitry employed.
