Notes:
1. The nominal thermal resistance of a display mounted in a socket that is soldered onto a printed circuit board is
Rθ_JA = 50°C/W/device. The device package thermal resistance is Rθ_J-PIN = 15°C/W/device. The thermal resistance device pin-to-
ambient through the PC board should not exceed 35°C/W/device for operation up to T_A = +100°C.
2. Voltage values are with respect to device ground, pin 6.
3. These displays are categorized for luminous intensity with the intensity category designated by a letter code located on the back of
the display package. Case temperature of the device immediately prior to the light measurement is equal to 25°C.
