Max. external voltage:
Maximum voltage to be continuously given to component in the dark.
Dark resistance:
Refer to the resistance ten seconds after the 10Lux light is shut up.
Max. power consumption:
Maximum power at the environmental temperature 25℃.
Light resistance:
Irradiated by 400-600Lux light for two hours, then test with 10Lux under standard light source A(as colour temperature 2856K). γ
value:
Logarithm of the ratio of the standard resistance value under 10Lux and that under 100Lux. Lg(R10/R100) γ= =Lg(R10/R100) Lg(100/10) R10,R100 are the resistances under 10Lux and 100Lux respectively. ________________________________________________________________________________________________________ Page 2 of 5
