Other name: LDR, Light Dependent Resistors, CdS Photoresistor 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).
γ value: Logarithm of the ratio of the standard resistance value under 10Lux and that under 100Lux.

• γ = Lg(R10/R100) / Lg(100/10) = Lg(R10/R100)

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