Measuring Conditions :

1.Light Resistance:
Measured at 10 lux with standard light A (2854K-color temperature) and 2hr preillumination at 400-600 lux prior testing.

2.Dark Resistance :
Measured 10 seconds after closing 10 lux

3. Gamma characteristic:
At 10 lux and 100 lux and give by

Gamma=log(R10/R100)/log(R100/R10)=log(R10/R100)

R10,R100:resistance at 10lux and 100lux.

4. Pmax:

Max power dissipation at ambient temperature of 25 Celsius Degree.At higher ambient temperature,the maximum power permissible may be lowered.

5. Vmax:
Max voltage in darkness that may be applied to the cell continuously.

6. Spectral peak:
Spectral sensitivity of photoresistors depends on the wavelenth of light they are exposed to and in accordence with the fig right. The tolerance of spectral peak is ±50nm.
