CDS Photo Resistor / LDR Light Dependent Resistor
Light Resistance:
Measured at 10 lux with standard light A (2854K-color temperature) and 2 hr preillumination at 400-600 lux prior testing.
Dark Resistance:
Measured at 10th seconds after closing 10 lux.
Gamma characteristics:
Under 10 lux and 100 lux and given by y=log(R10/R100)/log(100/10)=log(R10/R100) R10, R100: resistance at 10 lux and 100 lux. The tolarance of y is ± 0.1.
Pmax:
Max. power dissipation at ambient temperature of 25°C. At higher ambient temperature, the maximum power permissible may be lowered.
Vmax:
Max. voltage in darkness that may be applied to the device continuously.
Spectral peak:
Spectral sensitivity of photoresistors depends on the wavelength of light they are exposed to and in accordance with figure ‘Spectral Response’. The tolerance of spectral peak is ±50nm.
