Product Overview
The Senba LDR Sensor, also known as a Light Dependent Resistor (LDR), is a semiconductor device whose conductivity changes with light intensity. This characteristic allows for the creation of light-sensitive resistors in various shapes and with different light-sensitive areas. These sensors are widely used in applications such as toys, lighting, and cameras, offering features like high sensitivity, fast response speed, good spectral characteristics, and reliable epoxy encapsulation. They are integral to automatic light metering in cameras, photoelectric control systems, indoor light control, alarms, industrial control, light-controlled switches, and light-controlled lamps.

Test Conditions:
- Maximum Applied Voltage: Maximum voltage that can be continuously applied to the component in darkness.
- Dark Resistance: Resistance value measured 10 seconds after turning off the 10Lux illumination.
- Maximum Power Dissipation: Maximum power dissipation at an ambient temperature of 25.
- Bright Resistance: Test value measured under 10Lux illumination from a standard light source (color temperature 2856K) after 2 hours of 400-600Lux illumination.
- Value: The logarithm of the ratio of standard resistance values at 10Lux and 100Lux illumination. = Lg (R10/R100) / Lg (100/10) = Lg(R10/R100). R10 and R100 are the resistance values at 10Lux and 100Lux illumination, respectively (tolerance of is 0.1).
Packaging and Precautions:
- This product uses environmentally friendly packaging. Small packages contain 100 pieces, and large packages contain 1000 pieces.
- Avoid storing the light-sensitive resistor 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.
