Test Conditions
- Maximum applied voltage: The maximum voltage that can be continuously applied to the component in darkness.
- Dark resistance: Resistance value measured 10 seconds after turning off the light to 10Lux.
- Maximum power: Maximum power dissipation at an ambient temperature of 25.
- Bright resistance: Test value under 10Lux light from a standard light source (color temperature 2856K) after 2 hours of illumination with 400-600Lux.
- Gamma () value: The logarithm of the ratio of standard resistance values at 10Lux and 100Lux illuminations. = Lg (R10/R100) / Lg (100/10) = Lg(R10/R100). R10 and R100 are the resistance values at 10Lux and 100Lux illuminations respectively (tolerance of is 0.1).
Packaging and Precautions
- This product uses environmentally friendly packaging materials. Small packages contain 100 pieces, and large packages contain 1000 pieces.
- Avoid storing photoresistors in humid or high-temperature environments.
- Soldering time should be as short as possible.
- Ensure the lead soldering position is at least 4mm away from the ceramic base.
