Caution : If the absolute maximum rating of even one of the above parameters is exceeded even momentarily, the quality of the
product may be degraded. Absolute maximum ratings, therefore, specify the values exceeding which the product may
be physically damaged. Be sure to use the product within the range of the absolute maximum ratings.

Remark :
Maximum power consumption
Pmax = VFD driver dissipation + R
L
dissipation + LED driver dissipation + dynamic power consumption
Where
segment current = 3mA, grid current = 15mA, and LED current = 20mA
VFD driver dissipation = number of segments x 6 + number of grids/(number of grids + 1) x 30(mW)
R
dissipation

LED driver dissipation = number of LEDs x 20 (mW)
Dynamic power consumption = V
