The LTST-C21RTBKT consists of a plastic housing with embedded LED components. The LED emits light when an electric current passes through it, with the intensity and color determined by the semiconductor materials used. The housing protects the LED from physical damage and environmental factors. This indicator operates on low voltage, typically between 2V to 5V, depending on the specific model. It is designed for surface-mount technology (SMT), allowing for easy assembly onto printed circuit boards (PCBs). The LED's brightness and color consistency are maintained across a wide range of operating temperatures.
