φ3

PROD 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)

Overview

A photoresistor is a resistance made of a semiconductor material whose conductivity changes with the change of illuminance. This feature is used to make photoresistors of different shapes and light-receiving areas. Photoresistors are widely used in toys, lamps, cameras and other industries.

Feature

★ Epoxy encapsulation

★ Good reliability

★ Small size

★ High sensitivity

★ Fast response

★ Good spectral characteristics
