Remended Operating Voltage (DC) Max. Background 3 Sensitivity 4 Typ. NOTE: 1This is the maximum momentary current that can be handled if its full width at half maximum is less than 10 µs. 2If the tube is operated near this or higher, the service life is noticeably reduced. Use the tube within the remended current values. 3Measured under room illuminations (approximately 500 lux) and remended 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. 4These are representative values for a wavelength of 200 nm and a light input of 10 p W/cm2. In actual use, the sensitivity will vary with the wavelength of the ultraviolet radiation and the drive circuitry employed.
