Notes

(1)

Rated voltage P x R .

(2)

For values < 10  the upper limiting temperature is 155 °C. The power rating is correspondingly lower and can be calculated by R_th.

E.g. for WK8 - R_this 60 K/W; to calculate power P for < 10R; T_ambient= 25 °C

P = T_{Upper Limiting}- T_Ambiant/R_th= (155 - 25) / 60 = 2.16 W
