Test condition
Maximum applied voltage: the maximum voltage that can be continuously applied to a component in the dark;
Dark resistance: resistance value of 10 seconds after 10Lux illumination is turned off;
Maximum power consumption: the maximum power consumption when the ambient temperature is 25℃;
Bright resistance: After 2 hours of irradiation with 400-600Lux, the test value under 10Lux light of standard light source (color temperature 2854K);
Gamma value: The logarithm of the ratio of the standard
resistance value at 10Lux and 100Lux.

Matters needing attention
1. This product is packed with environmentally friendly materials, 50 pieces of small packaging, 200 pieces of large packaging;
2. Avoid storing the product in humid and high temperature environment;
3. It should be stored in a non-erosive gas, otherwise it will lead to oxidation of the tin layer and decrease of weldability.
Therefore, after opening the package should be used as soon as possible
4. Working environment humidity ≦95%
5. Welding time as short as possible; Soak the tin liquid (Sn63 Pb37) at 230℃ to 5mm away from the CdS photoresistor body, and maintain 3-5s.
6. Note that the lead welding position should be more than 4mm away from the ceramic base.
