Test Conditions

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).

γvalue:

Logarithm of the ratio of the standard resistance value under 10Lux and that under

100Lux.

γ=

=Lg(R10/R100)

R10,R100 are the resistances under 10Lux and 100Lux respectively.
