● Light Resistance :

Measured at 10 lux with standard light A

(2854K-color temperature) and 2hr.

preillumination at 400-600 lux prior testing.

● Dark Resistance :

Measured at 10th seconds after closing 10 lux.

● Gamma characteristic :

Under 10 lux and 100 lux and given by γ = log(R10/R100) / log(100/10) = log(R10/R100)

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

The tolerance of γ 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.
