4) The operating voltage limits Umin. and Umax. depend on the ambient temperature in accordance with:
Umin. (t) = K1 x Umin. (20°C) Umax. (t) = K2 x Umax. (20°C)
| Coeff. t | 20°C | 30°C | 40°C | 50°C | 60°C | 70°C | 80°C |
| K1 | 1.0 | 1.05 | 1.09 | 1.13 | 1.17 | 1.215 | 1.255 |
| K2 | 1.0 | 0.93 | 0.86 | 0.79 | 0.705 | 0.615 | 0.5 |
t = Ambient temperature
K1 K2 = Factors
Umin. = Min. voltage at ambient temperature t
Umax. = Max. voltage at ambient temperature t
