Photo Resistors

Photo Resistors

  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 at 10th seconds after closing 10 lux.
  3. 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.
  4. Pmax: Max. power dissipation at ambient temperature of 25°C.At higher ambient temperature,the maximum power permissible may be lowered.
  5. Vmax: Max. voltage in darkness that may be applied to the device continuously.
  6. Spectral peak: Spectral sensitivity of photoresistors depends on the wavelength of light they are exposed to and in accordance with fig 2. The tolerance of spectral peak is ±50nm.
