Description
12mm 12528 LDR (Light Dependent Resistor) – 10k–20k Ω
📄 **Description:
The 12528 LDR** is a 12mm diameter cadmium sulfide (CdS) photoresistor whose resistance varies inversely with light intensity. With a typical resistance range of 10k to 20k ohms in darkness, it becomes highly conductive as ambient light increases, making it ideal for detecting and measuring light levels.
This component is widely used in light sensing circuits, automatic lighting controls, and various light-sensitive applications.
