Model:φ3
Maximum Applied Voltage: the maximum voltage that can be continuously applied to a component in the dark
Dark Resistance: resistance value at 10 seconds after 10Lux illumination is turned off
Maximum Power Consumption: maximum power consumption when the ambient temperature is 25 ° C
Bright Resistance: after 2 hours of exposure with 400-600Lux light, the
test value under 10Lux light of standard light source (color temperature
2856K)
γ Value: logarithm of the ratio of the standard resistance value at 10Lux illuminance to 100Lux illuminance
γ= Lg(R10/R100) /Lg (100/10) =Lg(R10/R100)
A photoresistor is a resistor made of semiconductor material whose
conductivity varies with changes in illuminance. This property is
utilized to manufacture photoresistors in various shapes and with
different light-receiving areas. Photoresistors are widely used in
industries such as toys, lighting fixtures, and cameras.
Epoxy encapsulation
Good reliability
Small size
High sensitivity
Fast response
Good spectral characteristics
Applications
